“Better to start with a free form structure than to eagerly create one that turns out to be wrong.” I learned that lesson the hard way.

At company after company I have dealt with confusing messes of deep inheritance hierarchies, sometimes 10-15 levels deep, where each subclass adds just a couple of lines of code. The prime consideration was keeping the classification pure in a philosophical way, like we were inventorying the animal kingdom. A good portion of the developer efforts were targeted towards dealing with the structure of these classifications and not getting any actual features done. Factories that make factories. Singletons with pages of boilerplate to do one simple thing, no object ever necessary in the first place.

Spot on. Anyone who writes lots of JavaScript, Python, Ruby or Go and then dips into the C# or Java world knows exactly what this nonsense feels like. It's developers scratching their own itches of systems level thinking, trying to create the ultimate "system" to solve code complexity. Like a mini-game where they're trying to create an encyclopedia for the world. But by trying to systemamitize away complexity they create even more of it. Now you need your devs to understand dozens of different "design patterns" that supposedly decouple your program and make the codebase easier to work with. Why then are they so complex, require constant abstract thinking and make the codebase even more complicated to work with? Why does every design pattern come with the disclaimer that it doesn't actually fully decouple anything and that it's just a different form of coupling? The coupling comes from needing the cross cutting code. There is nothing we can do about that problem other than make it easier to understand for our developers. Creating all sorts of wacky service locators, inversion of control containers, factories, dependency injectors doesn't decouple anything.

I've known some very narcissistic programmers who write this kind of code for huge organizations like banks. Usually they have zero experience outside their language of choice from 15 years ago and think "standards" and "good practices" are gospel. They usually have zero creativity and think things like "you should use DateTime to store a year value because it's made for it" instead of using a bleeping int. That guy built a framework for every single little thing, and thought Microsoft invented marshalling. He literally could not define the term outside the context of the .Net Framework. And big companies paid him well to write overengineered crap. Of course, he constantly bragged about all this amazing stuff he'd learned 'at the top.' 😂

No worry, you have nothing worthy to understand from this video. Better read Gang of 4, Martin Fowler, Robert Martin and other references. His whole argumentation, especially about encapsulation (eg from: 23:04) , is extremely biased and perverse. His arguments are based on object graph examples which are badly designed in first place. If you respect reasonably SOLID and general OOP principles, you should NEVER get that kind of spaghetti object graph in first place. Then the code would be encapsulated already (SRP, DIP, ISP, LSP, demeter law, and so on...). Then you wouldn't need to encapsulate non existing spaghettis such as he's attempting to, to make his point about how "OOP is bad". And about his statement: "Abstraction = simplified complextity; abstract = hard to understand". Well why abstraction simplifies complexity is because we do NOT have to understand what is abstracted if it's abstracted, so again a perverse argument... Furthermore, abstraction is not more related to OOP than to procedural or any other paradigm. "Mistery why industry tends by far toward OOP"... Did you try developping then maintaining complex enterprise applications (changing often) in procedural, compared to OO? That wouldn't be a mistery anymore for you then... "Procedural languages are more polymorphic than OO languages", lol, special mention for that collector one... And the same goes for a lot of his arguments...

@Clément Cazaud Have you seen the guy's video where he breaks down four real OOP examples from proponents of OOP and how they could be rewritten in procedural form? I think one of the examples in that video was from Uncle Bob (Robert Martin). To be clear, I really respect Uncle Bob and I've bought and read his Clean Code book (his chapters about comments, naming things, and code rot really convinced me to kick some bad habits while programming), but I think the guy's video brings up an interesting point on how one example of Uncle Bob's code being convoluted because it was written in OOP fashion. I'm still relatively new to programming, so my opinion probably isn't really worth much at this point.

I've been in the industry for 20+ years and thought I would share my experience. These are just tools. Imagine 2 handymen arguing that the hammer is THE tool and another claiming a screwdriver is THE tool. They go back and forth pointing out the inadequacies of the other while showing the advantages, elegance, power and more than anything personal aesthetic preference for their preferred tool. Meanwhile the thousand other handymen in town use both tools alongside each other as well as a dozen other tools in their toolbox. Out of the 2 arguing handymen one is certainly more right than the other, though no one is likely to know which. All the other handymen in town know how and when to use specialized tools and they are getting paid the same if not more than the 2 arguing. Learn what you can, try it out, use it when it applies, get paid. School is just one of the tools along the way. There are many problems with the educational system, but that's too much to cover here. What the education systems effectively do is certify you can solve problems and you can see things through. You will learn more about effective design in your first year working than you did in the 4 years to get your undergrad. The learning never stops. Your intuition will continue to develop through your entire career. Listen and extract from these hot takes but please don't take them as gospel. Mostly don't take anything as gospel, just figure out how things are useful. Enjoy your journey.

Hey, just want to thank you for this video. This explained something really well that I’ve noticed from trying to grapple with existing codebases at work and have intuited as a kind of encumbrance. Chasing classes down gives me a headache - when I want to understand what code does ideally I want it as sequential as is sensible so that I can follow the changes of values and potentially interrogate by pulling values out at different stages. Having classes built on classes built on classes all the way down means that often I get to the functionality I want but then can’t find weird the values get into that piece of functionality in the first place as whilst I’ve followed the hierarchy down one leg I now need to follow it up another! I’m a Data Engineer but have come into it without a degree in any computing field, and many of the things you’ve mentioned in this video I have come to on my own. Such as passing global variables into functions explicitly not just calling them for the sake of it. I totally agree that there is a place for objects/classes for data structures makes sense but not making all functionality Objects. DataFrames are excellent for my work and what they do makes sense, but that doesn’t mean that style of structure makes sense for everything.

It really depends on the problem. I programmed the first ever constructed OOP-language in 1970 which was SIMULA and has since then used various OOP-languages including Object Pascal, Java, Javascript, C++ and Ruby. Some problems are really difficult to tackle without objects and for some others objects just distract from the task what you actually want to achieve. Nowadays I mostly use procedural programming but occasionally add in objects for special tasks. It just boils down to common sense when to use it. I agree to that OOP is overused and often just adds confusion when one wants to understand what the code of others actually do.

I am a mother one of those old timers - started programming back in 1980. That was with an HP calculator with 15 lines of code and 8 memory registers. There were also the ‘optical cards’. You scribble your program onto cards by selecting various numbers, send them off to the mainframe, then a few days later back comes a printout. No keyboards. No monitors, and the printout just as likely to say ‘syntax error on card 3’ as it is to provide any meaningful result. Imagine, A code, run, test cycle measured in days! I have been through almost every ‘revolution’ there has been. Several times. These new fangled technologies come and go out of fashion on roughly a 10 year cycle, just with new TLAs. I have also been responsible for pushing a fair few of them myself as well as resigning myself to ‘here we go again’. One thing to keep in mind is the Turing Machine. Turing proved that all computers, and all languages, are equivalent. Pretty much, once they can do basic logic, then all languages have equal expressive power. Anything you can do in one, you can do in another. So arguments about procedural vs OO vs Functional are moot. I can write an OO compiler using a procedural language and vice-versa. Not efficient, perhaps, but doable. So what it comes down to, as mentioned in this video, are the practicalities. In practice, in a real team, with real people with real business problems and challenges. The efficiency of writing and maintaining the code. The efficiency of new hires getting up to speed and the risks of losing people with ‘the knowledge’. Building a system that is easy to adapt and extend that Ames the users/customers happy. This video singles out ‘excessive OO’ or ‘extreme OO’ as a bad thing - in particular encapsulation. Quell surprise. Excessive anything is a bad thing! For the comp sci students out there, just remember all these technologies are tools. To be successful in a programming career you will need to master a fair few of them. No real world problem, worth solving, can be done well with a single tool. As a wise boss said to me once, ‘this is technology. With the right tool it will go 100 times faster’. This was when I was writing my own ORM layer - not realising there was already a library to do that. Similarly, I once had 85 lines of procedural code replaced with a single line of (damn clever) SQL. Being a programmer is a bit like being a doctor. You can’t solve every problem with a scalpel. You can’t solve every problem with antibiotics. Every person is a bit different. You need years of training and a wide variety of diagnostic as well as preventative as well as curative tools, medicines, machines and hands on experience - book learning alone will not cut it. The main factor for deciding what tools to use is the Problem Domain. One thing I have noticed, time and time again, is that the ‘best’ computer code accurately reflects the Domain it is working in. I guess it is called DDD these days. From that perspective, and getting back to the video, your encapsulation level should reflect the natural encapsulations of the domain you are working in. Though this is more of a heuristic than an absolute rule. Let’s call it ‘Domain Oriented Heuristic’ programming or DOH programming for short. 👍

Shirom Makkad mmm. Well, Domain Driven Design is the thing to search for. Most custom written (let’s say in-house) systems, built to support a specific business, end up with libraries, objects and data models that reflect the nouns and verbs and datasets that the business users use themselves. Encapsulation is also reflected in the various departments and functions of the business. Where this gets really interesting, is dealing with mergers/takeovers and internal re-organisations. Over time, what happens is that the system moves towards an ‘industry standard’ model - particularly as engineers and users are hired and fired between companies but within that industry.

graham287 yeah - spent quite a few years ‘managing’ and ‘enterprise architecture’ but back to programming now. Mainly Python - which I think is now my favourite language. Mainly because it ‘defaults’ the right way, most of the time and automatically deals with edge cases. So less code.

As a Software Developer with over 20 years in, having developed in many different languages using multiple methodologies and patterns, this was an interesting presentation, Thank You Brian! The pitfalls you point out and complexities are absolutely real. While I don't think that falling back to the 90's is the answer, as you seem to insinuate, your argument points to something very important, which is too keep architectural and design concerns at the forefront as you write and modify code. "Bolting on" without understanding the design of a program is a fast way to create spaghetti, not matter functional or OO. I find that good program layering and being familiar with Design Patterns is crucial, and helps avoid some if not all of the pitfalls. If I am a doctor doing surgery, I better know how the organs (objects) are laid out and connected (patterns). Just knowing how everything functions is not sufficient in a complex system. As far as Agile goes, that is not a coding "thing", it is a shift in the way we think about building and maintaining things, but should also involve many non-coders in order to correctly set expectations about what gets done when. I will be watching some more of your content. There are some great titles, and you obviously have a lot of real world experience to draw from.

You're right to bet in design and architecture, but it doesn't change the fact that once in implementation you'll face the dilemma for full/partial encapsulation as he mentions around 25:00 - full encapsulation results in lots of additional classes created to help you deal with state (design patterns). Those classes are not related to the problem being solved. They increase complexity because it doesn't make the code any easier to read and leads to poor performance - partial encapsulation results in spaghetti code.

1) OO was proposed as a solution to problems inherent in functional, top-down design. It was first implemented in languages like Simula (1960s) / Smalltalk (1972), Python (1991). Java wasn’t created until 1996, OO was well established by then. 
OO was adopted after struggling with many problems in industry, having a long theoretical debate, then doing some experimentation. 2) Brian fails to mention the problems with functional / procedural design. Top level interfaces become very fragile without encapsulation, Iterative development often leads to repeated refactoring of the higher level interfaces. Reuse within programs is common, having every consumer maintain its state for an interface adds complexity and will become unwieldy at scale.
 It's also simply unnecessary. And no, making the shared state global is not a good solution. 3) Test driven development is not consistent with OO. Test driven development was pretty much a fad imposed by managers. It is just design by interface applied to testing with some other rituals built in, it has more in common with functional design than OO. It suffers from the same shortcomings. 4) Brians biggest mistake is he pitches functional and OO as opposite one another. OO is not about data modeling, or data driven design, or modeling real life objects. The early theoreticians overemphasized the data modeling aspect of OO because they were contrasting it with the prevailing design style at the time, functional design. Had data modeling been popular instead, OO would have been described in terms of designing for behaviors. OO is simply the bundling together of functions and data, with some support for minimizing duplication and access. That ideal balance of functional and data-oriented styles you keep alluding to - that is a good use of OO. OO is also totally compatible with FRP, infact FRP is used alongside objects in most code implementations of FRP. It actually compliments OO very well as it solves most of the state management problems. And FRP is an entirely separate paradigm from functional / procedural programming that dominated in the 60s - 70s. 5) Your object graph is just an undirected mess. You claim the only alternative is a hierarchical structure, this is simply not correct. You can maintain a cyclical object graph and trigger update cycles... you can have mid-level objects that manage lifecycles, and then have an object-graph of them at scale, or a hierarchical structure of them. You can come up with bad designs for anything, this is not a criticism of the paradigm. 6) refactoring code into smaller components is a functional technique, I'm not sure where you got the association with OO. Many functional programmers advocate super-small functions that confuse people ... I've never seen OO designers advocate using tons of super small classes. That's just bad design, the fault of that is on the programmer, not the paradigm. The programmer has to choose the right granularity. 7) Inheritance is used all over the place, there's just a good and bad way to use it. There is not some uniform consensus it should be avoided. When you use inheritance you just have to make sure that the base class won't be torn in different directions. Usually this means using it on smaller components without complex responsibilities. 8) OO is meant for large projects where architectural issues matter. Java was designed specifically for this purpose. If your application is 3000 lines, you might not need OO. You might be able to get away with using global variables at that scale (though if your application grows much larger you're pushing it). In an enterprise scale codebase where you have 10 million lines, no architect would ever design for reliance on global state, this would only result in complete chaos. You exaggerate the flaws of OO without providing a real alternative, and don't address the scalability problems in procedural programs at all, hardly.

After bouncing off OOP and coding in general and picking things back up, I find myself leaning towards this stuff you're saying, even though I'm not sure I understood all the context myself. I REALLY like that concept of a use x,y demi-function. It scratches an itch I had since the very first time I learned what a function was, and needs a lot less jury-rigging than a modified for loop.

The biggest problem I have with this video is that it completely forgoes one crucial aspect of development - testing. Not having modular components and having "God functions" that do everything in one place makes your software really hard to test, you can't really test individual bits of logic and it will become a nightmare to debug your functions if you need to make even tiny changes. Besides that this obviously introduces a very high barrier of entry for understanding your code, there is so much that a human brain can process and keep track of while reading and grasping the full picture will take much longer than if the same logic was split into separate components, and in many cases the ability for your colleagues to quickly understand what the code does without delving too deep into implementation details is really important, they in general would have other shit to do and spending an hour to understand what a function does is not a good use of their time

Working on large, highly complex projects, I've found the opposite to be true. Human brains struggle with interlocking complexity, not cardinality. We use the functional core imperative shell apporach -- even a non-technical person can open the "shell" procedure, read it top to bottom and understand what it does, hell they might even be able to make minor edits. Uncle Bob-style OOP does the opposite -- it fragments business logic into as many small, individually meaningless units as possible, making it much harder to build out a mental model in your head. Our code practically has a UML sequence diagram built-in, and our engineers love it.

Just found this video, found it really informative and I'm glad someone pointed out that OOP isn't some magical methodology you learn and becomes default. From what I found with OOP is that most cases it's either a) Trying to be an overengineered struct, or b) Trying to be an overengineered function (or group of functions). It seems most people use them because it's normally the most advanced thing they learnt and they assume "it's what the real programmers do" (Like a kid mimicking adults).

It also really helps to expand your program, by limiting what you need to change. What he is asking for can easily be done with C code, but history has proven him wrong, procedural is inferior to OOP, when one uses OOP correctly, like don't use polymorphism for what is basically a switch case, it should be used when the data structure fits the split into more classes with a common base.

The reason for this is that most server side codes needs to be entirely re-entrant, so storing state (other than configuration ), is a no no. State ends up in databases (of various forms ).

In reality though the "combination of objects and functional programming" is already the real world way people use OOP and i might argue the standard. The problems with OOP are really just strawman uses of OOP. In the real world, encapsulation and abstraction are only used if it is beneficial, like reducing complexity and improving readability.

Leverage the strengths of OO (like polymorphism, high cohesion, low coupling) but minimize its pedantic usage (like unnecessarily complex inheritance trees for the sake of OO purity).

It's a cool idea to structure long functions using that, although I'm not sure how I feel about the arguments being at the end rather than the beginning. The use syntax would be nicer.

Yeah, as a computer science student that took the supposed rules of the OOP paradigm and the supposed virtues it provides, I often wondered as the things I programmed became more complex just how on earth people tolerated writing code like this. I could whip up something fairly complex quickly with a procedural approach, but trying to force everything into boxes I was supposed to keep separate just paralysed me and I spent more time shuffling those boxes around to keep things neat than getting stuff done. All I could think was "this is so much extra work, but I guess it's good practice. It'll be worth it in the future, etc." So, can't say I was particularly impressed when I started looking into real world OOP source code and found out none of these rules are actually followed and people just threw around references to objects that were specifically there to allow global access to references of virtually every other object in a giant clusterfuck void of hierarchy. What's the point?! Now I still have to micromanage state myself, because your code will let me do things I probably shouldn't do, but I have no chance of understanding what's actually going on because most of your code is still pretending to respect encapsulation and is just juggling references to references which is now nothing more than a maze between me and the actual data or functionality.

Maybe to someone who doesn't know how to read the code itself, or gets lost in it without plain English. Is it pointless busywork at best or a cluttered mess at worst to someone who doesn't need the comments? Absolutely. To be clear again, I'm not trying to say OOP practices are like writing needless comments. I'm just trying to illustrate how it can sometimes *feel* to work in OOP code written with a level of granularity that feels unnecessary. Like having an entire directory designed to contain a single file because to some people that's "more organised," when to others it's needless convolution.

Interesting. I made a total-conversion ARPG mod for an RTS recently and found dealing with class organization to be the key struggle. The code, though powerful in the context of the mod, ended up as spaghetti as anything outside of the object's scope required additional subclasses or types to control things since they didn't necessarily belong to that class, or could exist in one class or another since they shared featurization (in game dev, this is probably a common issue as features are added). For every added layer of complexity I'd wager the effort to make a change increased by 3 to 4x (which is pretty crazy). It starts to make sense why the AAA titles coming out today are a mess, given the size of the stack at play and the corporations fiddling with them. Nightmare fuel.

As someone relatively new to programming, I appreciate how thoroughly you managed to explain your argument in this video despite all the jargon that was involved. It also taught me more about how and when to use both procedural and OOP, so thank you for that.

I disagree, because cognitive complexity is a real thing. Our human brains can only hold so much in memory at once, so it is our goal to design a software architecture that optimizes for that. I can say definitively from my own experience that giant procedural code I wrote in my early years is far more difficult to read and comprehend. Once you study it for a while it becomes understandable, but only after a while. Code where I broke up into smaller pieces is much faster to read and comprehend, and I make fewer mistakes with code written like this.

Yes, cognitive complexity is a real thing. But OOP does not help with it. All it does is throw the performance aspect out the window so that the problem you are trying to solve is a simpler one. Dumbing things down means you aren't solving the same problem anymore. For a given problem, if you aren't disregarding the codes performance, the problem is necessarily as complex as the problem is. You can't just willy-nilly group things up without affecting how the code runs. When you are trying to solve the more complicated version of the problem (which is not done for nothing, it is useful), thinking in OOP terms will not do anything useful.

I completely agree. I have always gravitated towards languages that support OOP concepts (Perl, Python, C++, VFP) and features but didn't force you into the model wholesale. My own style leveraged classes and objects but I still maintained function libraries when practical rather than forcing those into classes.

41:55 C++ has a solution for this: lambda functions, so instead of doing "use x, y { ... }", you do "[x, y] { ... }". It won't have access to any other variable than x and y. Edit: and it does exactly what you want, it makes clones of those variables, and if you really want to change them, you can pass them as reference for ex, with &x. It's really like having a function but without having to name one, and it can be placed anywhere.

This year, I took the plunge and decided to write an entire project using just functions and interfaces, in TypeScript. I had to stop and regroup a few times along the way, but the exciting thing is, the stuff I've had to learn along the way really seems more generally applicable - whereas a lot of the OO patterns and principles often seems like (as he says) a workaround or a bandaid. What you learn by committing yourself to this is much more general - simple techniques that work every time, not just for one specific problem or scenario. I have 23 years of developer experience and pushing myself to go all in on this feels like leveling up - for the first time in a long while. I was on the fence about this video in 2016. I knew there was something true to it, but I had no idea where to start. It does have something to do with the language you're using - I was using mainly PHP, where functions and interfaces aren't really practical or useful the way they are in TypeScript. I don't agree with absolutely everything in this video. Part of me wonders if the author hasn't changed his mind about some of the finer points in this video over the years - we all grow and learn, right?

Having designed and implemented and programmed in many Common Lisp systems, I've always found everything newer to be worse and disappointing, and it is satisfying that functional+object programming is now finally getting the respect it deserves. Javascript seems the closest to what we had in the 1980's..which is both disturbing and hopeful. I almost wonder if the time is right to bring back Common Lisp, or the simpler subset like NiCL that I created. The last 10 years all I do is write microprocessor apps using C to run in chips that have memory sized in kB. It is refreshing to be able to see the entire app in a few pages of code. I don't think Common Lisp would work in this environment or I would have tried to get it working. I see the chips have gotten big enough that they are running micropython these days...never tried it.

Don’t fall into the hole too long. This is why I hate devs who argue between specialising and generalising.

And then a purely syntactic proposal "I would like to have this, cause I can't read code". You do understand, that you could just as easily use an anonymous inner function, pass parameters to it and say "this is self-contained" in the comment, right? But I guess you're just too busy, trying to tell us what every practicing coder knows, to actually bother making the best of the tools you have. "Nooo, we need a _very specific_ hammer for this _very specific_ nail, cause a regular hammer just won't do..." I am an average craftsman of the trade. I hate OOP. I hate Java. And I hate people in general. Specifically I hate tech bloggers, that try to be edgy but just end up riding the mainstream.

+SGresponse 1) A comment noting an inner function is self-contained is an OK half-measure, but language-enforced guarantees are better. 2) If you conflate FP hype with anti-OOP, then it might seem anti-FP is middle of the road among recent tech blogging. But a large silent majority of programmers pay no attention to tech blogging, and most of them are at least nominally doing OOP. I'm explicitly advocating for procedural programming regardless of imperative vs. functional. That's not fringe, but it's definitely a minority position held by probably less than 10% of all coders. 3) Yes, a big chunk of supposedly OO code barely follows the prescribed principles in even their weakest forms. That's a good thing. Very often, though, these pseudo-OO code bases make gestures at following the principles because the programmers feel guilty for not making their code "proper" OO like they learned in school. The end result is not as overly complicated as full OO but still overly complicated. More programmers need to hear the message that they can stop feeling guilty and just program the more natural procedural way. 4) You're a dick.

+Brian Will Addressing your response in no particular order: *4:* I indeed am a dick. Did I mention I hate people in general? That's a subtle hint. I am an absolute nightmare, cause I voice my criticism in such smug Dickness, that many people just see Dick and nothing else. Glad you're not one of them. I have gotten better over the years and raised my status from being an _intolerable fucking douche_ to just being a _dick_ , so this self-aware confession is not just means of avoiding the issue. I improve in small steps. *2:* The FP hype I don't conflate with anything because I stay as far away from any technology hype as possible. Every single thing that any larger group gets hyped-up about is ultimately totally impractical for non-edge-case use. This goes for OOP, FP, Prolog, Logo... anything. I'm criticizing you for saying that you take a fringe position - not because currently "FP is on the rise and OOP is passe". I'd be criticizing your mistaken identity even if OOP was _the shizz_. Because ultimately everyone, that had ever experienced in practice the tenets of OOP as they were intended in theory, knows the stuff you say and adheres to it. _That_ makes your opinion middle of the bell curve - not the fact, that the hype train moved away from OOP. Going Procedural is like using MS Windows - it's not glamorous, not glorious, doesn't push any boundaries, you won't write a thesis about it, nor a smug blog post that proves you are awesome because of using Windows. No - you may use Windows, because it has a low entry barrier or because you're used to it or it has all the functionality you need right now (and you don't care about what you'll need in 3 years time) - but mainly you use Windows because it works. Sometimes better, sometimes worse, usually "good enough" - still: it WORKS. And the same is true for Procedural programming - it's "good enough" to handle most cases you will ever need programming for. And people know this on an intuitive level. Meaning, again, *many people agree with you. You are not fringe, nor 10% minority.* You're somewhere in the 40-80%, depending on which company employees you'd interview. And if you're going to argue specifics, then theoretically yes - less than 10% of people holding this position will ever express it openly. Usually out of lack of self-awareness, rather than out of fear of ostracism. *1:* Yeah, it's great when the compiler thinks for you. I love strong-typed languages (no irony here - this one's sincere). But this - this is not the way to go. There are two additional arguments against this I can give, besides the most solid "specific hammer" one I already gave: Firstly Context and scope are a finnicky concept. You will learn that everything that's in {} brackets knows all of its surroundings but anything outside of these brackets won't get in. And that's fine, that's enough, that is working knowledge you get engrained in yourself so deeply, that you don't even consciously notice this assumption in your thinking anymore. And then comes some poorly written VB6 code, where no one bothered to dim the variables, so every single local "tempstr" variable is just a call for the global "tempstr", that god forbid you dare use in a subroutine and expect your local copy to be intact after you call that subroutine. And then you see javascript callbacks where you can switch up the context by virtue of one parameter and you then don't actually know what the current function call can see outside of it. And then you try to use "this" in a standard event callback and it goes south so fast, you're chewing on Antarctic ice before the shift is over. So in summary - don't mess with core concepts. It's unhealthy to have exceptions to rules when rules are the only thing, that can help you stay sane in an otherwise profoundly insane environment that any programming language is. And if your response is "if there already are exceptions - why not just throw in another one?" - please go read whatever your government currently uses as tax law. Go read it, understand it ALL and come back and tell me yet again, that exceptions to general rules are a good thing. I dare you. Secondly Languages are complex. When you said in your talk (paraphrasing) "Why can't we use something like _on this object I give you, enact function F_ ?" I was initially with you on this. "Yeah, why don't we?" I thought to myself. And then an answer flashed back to me: Parsers. You need the language expressive enough to code complex concepts in it, structured enough for the machine to efficiently parse and simple enough for an average shmuck from accounting to learn the basics in a month. Each new keyword adds complexity and reduces the viabilty of the latter two aspects. And while I may understand you're coming from some functional language where the list of keywords is roughly 30 items long, this notion will eventually sip into every popular language, adding to yet another intricacy to something like PHP (nearly 70 keywords) or C# (over 80). After finding what the keyword "yield" means in C# (for those interested: it's a bastard child of _"pointers are too hard for the average accounting shmuck, so we'll use references everywhere"_ and _"our container implementations are slower than C++"_ ). Learning "yield" was one of the contributing factors in my conversion to Satanism. But I digress... after finding "yield" I say *NO* to the notion that we should expand our languages with new features. No! Complexity should be removed, obscure features should be cut from language syntax and, by Jove, never a feature should be added that LIMITS what you can do using the same effort and already existing tools. That is just backwards. *3:* Here's the meat of the subject. The concrete, the Agenda. You see, I've dissed so much of your approach mainly because this is nothing new to me. And you seemed to be making a big deal out of it as if you were a Buddhist monk enlightening me about virtues of clean code and simplicity of life. But the stuff you said was nothing enlightening... Until. This key sentence: _"More programmers need to hear the message that they can stop feeling guilty and just program the more natural procedural way."_ . This is an Agenda. This is Purpose. This is... never mentioned in the video... right? Did I miss it? Did it fall somewhere in the cracks between the Java riffs and the syntax rant? But it is something new to me. Are there poor lost souls, that still think their code is crap just because one method has more than 30 lines in it? Or that their inheritance hierarchy is too weak, because it doesn't give space to every possible entity ever existing in the universe? And because of this they think they're unprofessional? Are there such people? If so - yes they need to be reached and slapped back into their senses. And I am fully in support of such an agenda. But why wasn't it stated explicitly? Is it because for a tech blogger having an agenda is usually viewed as overzealous? Or cultist? Or... unprofessional? If so, then I think more tech bloggers should hear the message, that they can stop feeling guilty and ashamed of their agendas. And just blog and make videos the more natural way - openly stating their intents and allowing viewers more broader context on their position in that way. PS: I should stop putting essays in YT comments. This is a chore to read.

***** If you assume that the people that come in after you will be sensible - then the comment is enough. However if you assume that they're the stupids, then pretty much you have to concede that they will fuck something up regardless of the language constructs we put in. Your point supporting the new construct is invalidated either way. And again: the visibility of the broader scope from the nested scope is NATURAL for all bracket-based languages. So making a keyword that will change this behavior would not only be pretty much useless - it would be detrimental. Granted: I can actually see one good use for this in code. When someone is writing code that's so shitty you almost expect to see it cross-cut through all the variables at any point and change them willy-nilly. Then seeing the sandboxer in there would be a blessing. Or leveraging it to do some runtime analysis on that crap code. But really: asking for a special syntax that _breaks general behavior_ (key problem for me), just because you're either shit at writing code or shit at reading it... I can't even express my feelings toward it properly - a mix of distaste and disappointment in one's craftsmanship. It's not even the fun kind of shit-in-code. It's the sad kind. Corbin Crutchley It wasn't both sides of the tale - you will see that in basic approaches to everyday coding Brian and me agree quite readily. If you really want a different side of the coin - look for someone who's into rigid OOP. I can't recommend anyone, cause I stay away from those zealots. Anyway: thanks. I find it rewarding that at least one person read my essay through to the end. Trevor Hart Being middle of the bell curve isn't a problem - that's true. Posing as if you were the fringe while being the average - that's what I challenged Brian on. I still feel like I was right, but it's up to you to make your own opinion on this.

Oftentimes I find that when a module gets to a certain size and complexity, my gut tells tells me it's time to refactor into several object classes. Sometimes it feels like I'm congealing the code I've written into separate piles, but over time I get an intuition about what data and functions belong to which classes. Fortunately, I learned the hard way to keep objects and calls strictly hierarchical. For myself, I have found OOP generally to be the best way to organize code. Having said that, I enjoyed your video and I should be able to find things I can use. Thank you.

Each paradigm has its place and use. There are situations that aren't very conducive to OOP, but there are a lot of places where it works really well. There are also a lot of uses where it actually makes things worse. The problem is that a lot of programmers aren't great at deciding when and when not to use objects.

the problem begun when programmers started to create abstractions instead of features. Features are "hard" things, I mean, you know what it will do, you know how it should do, you know the right way to it to do. Abstractions are, instead, "soft" things, it means that you will never know exactly the correct answer to solve a problem, even if you know the "hard" way to solve it. That's why we have the "over engineering" term on the abstract way, while in "hard" way, we don't nearly have it. May be the world could be a better place for new ideas if OOP didn't get so popular and accepted. Today that ones who knows how to do something in a "hard" way are considered lesser than that ones who have a nearly idea of how to make it, but in a "soft" way, and that's sad.

This video should be named "I have a bad understanding of OOP and I don't like it. 45 minutes of rambling." This was an utter waste of time, entirely infuriating and possibly harmful to many novice programmers. *Random stranger, before you watch, here is a run down:* First 18 minutes: Just opinions without any arguments or examples. Minutes 18 - 29: "I don't know how proper communication between modules is done. Software architecture frightens me. Manager classes are pointless. Yay anarchy." Minutes 30 - 33: "You have to write a class for everything you do! Someone said it and I didn't bother to understand 'when' and 'why', but it is stupid!" (Yes THIS is stupid. No one BUT bad programmers do this. Or giant corporation software architects, who are tasked to combine legacy apples with merger oranges into some big uber solution. They produce bad architecture, because they don't care on a personal level. i.e. "Fuck the SA in 3 years, who has to deal with this software, I'll step up in the corporate ladder or be in another branch or company by then.") Minutes 33-43: Nothing on the topic. It can be summed up with: "Use functions and consider code formatting. I wish I could write functions inside of functions, which act like functions outside of functions, but are not called functions." (probably to hide his obsession. Or maybe because he is not allowed to write private functions just below his public functions, because his supervisor is a code style nazi. Dude, stop working under idiots, plz.) Minutes 43-44: He criticizes books like "Design Patterns". Should've read Software Architecture for Dummies first. Brian Will, wtf. Don't give up, yet. The beginning is hard. Maybe you should check out "static functions" (They give you the "namespace + bunch of methods" functionality you asked for). If you are concerned with states of objects, which are called by several objects, check out "semaphore" or just use setters, as OO advices, because it gives you the freedom to implement priority/concurrency/multithreading/networking any way you like. Don't ditch objects for structs+functions. They help you. From yourself.

The problem with his video is, that he basically takes the extreme ideas behind OOP, (like "everything is encapsulated") and rambles on about how bad ideas they are, without giving any real arguments to why they are bad (just some hints in that general direction)and without providing examples either. Also he uses plain false information, e.g. that inheritance is generally viewed as bad practice. This is plainly wrong. Inheritance is viewed as both overused, potentially dangerous(hard to use correctly) and misused, but it is not bad. There are situations where it really helps, and sitatuions where it does nothing but hinder you, because you have to use a really ill-fitting abstraction to use it. And finally, my last and biggest complaint: He is treating this as if it was an Ideology! I don't really know how to treat someone who does this, because of how idiotic this is. This is just as valid as saying: "I am a carpenter, and using a Hammer is an Ideology!" OOP, functional programming etc. are tools, not ideologies. The only valid point he briefly made, (just before he continued ignoring just that point) is: OOP and other styles do not exclude each other. They are like hammer, saw and screwdriver. No carpenter in their right mind would ever proclaim: "From this day forth, I shall only use my screwdriver, for it is the most holy of tools, and all the other tool shall be banished from my domain, as I have no use for them". Similarly, I have not met a single programmer worth their salt who thinks that a fanatic degree of OOP is needed to solve a problem. Btw, I mean real programmers, not people who can technically write in Java for 2 months and still have their training wheels on. They see OOP as a tool in their collection, a tool they can use, as well as ignore, whenever they see fit. TL;DR: The video uses a lot of strawman arguments, by treating OOP like an ideology, instead of the simple tool that it is.

This is a long video and pretty interesting but I'm not sure if it covered my main concern with non-object oriented programming which is how do we do a better job of avoiding side effects or just really messed up shared state? I'm wondering if the solution might be to use object oriented programming specifically when it relates to data but not to "responsibilities". For example you can create an object to represent some type of state that manages that state, including an interface for a database. But you should not create classes to do really anything else other than manage state... For example no factory classes, no controller classes, no classes responsible for some portion of functionality such as a servlet, etc etc.

A great video, well worth the few minutes to watch. It certainly removes the guilt about not following the university taught methods of OOP. Our code today is a mix of procedural, functions, and very limited classes. It’s a style we ‘fell into’ after suffering the pain of trying to make OOP work for all applications. This video vindicates are choices and makes them more defensible if code was ever audited.

Cool video. I've definitely run into the problems you talk about at work but I always just thought "eh whatever I'm stuck with this" and tried to band-aid them as best I can like you discuss lol. The "excessive splitting" problem is particularly relevant, because we have these dogshit code sniffers that complain if any one particular function has too much stuff happening. I find myself needing to split up functions into building blocks that literally don't ever even get used anywhere else besides that one original function anyway, which feels pointless. That being said, I find your solutions to still sort of just be "do OOP better." In my experience anyway, all of your suggestions at 37:30 are things I've read and applied to a programming style that is still OOP at heart, discovered through an essential goal of "I want to do OOP better" - but maybe that's OK? In fact, the entire "Functions" section of the video seems to encapsulate what I just talked about, where a function should be split up in a way that does not make its components any more "widely usable" and instead is just breaking up the big function for readability. Perhaps I missed something, but I still really feel "procedural programming" as you described it is "doing OOP better." Which again I think is fine! But the video title then becomes a bit disingenuous, idk

The complaints are valid but I can't agree with all the suggested fixes.

Actually C++11 has the `use` feature that you show. In C++ lambdas doesn't capture (see) all variables from enclosing scope, you need to declare them explicitly in capture list. Instead of writing `use a, b { }` you end up writing `[a, b] {...}()`. Example: `const int a = 2, b = 3; const int c = [a, b] { return a + b; }();`

To me a well thought out and designed OO program is easy to work on (whether you were the original programmer or not) and to extend. In my experience, the nightmares arise from programs that started as one thing and grew to something else or worse they were extended by a programmer who took shortcuts and no longer adhered to the original OO design. I’ve worked with both well designed OO and procedural programs and in my experience I have always found it so much easier and enjoyable if it’s OO.
