She's got a decidedly unscientific certainty to the statements she makes. Her opinions are just that and delivering her opinions as obvious facts is deceptive. Quantum computing has enormous potential. It may be expensive and may always be expensive and it may be noisy and this may never change but even with those problems it has enormous potential. If it's at all useful it can do things that seem like total magic right now. This power is known and this knowledge is what causes the seekers to pour so much time, effort, and money in. And Sabine is doing something very sneaky here. She makes a video that contains inflammatory rhetoric about a topic she knows little about and finishes it off by turning into a saleswomen hawking a predatory product that promises it can teach you how to think. And she gets paid for it. Unknown to most, the reason this video exists is to get Sabine paid. The only reason. This is why it is inflammatory. So you'll watch it. It's not inflammatory so it's closer to the truth. The topic isn't chosen because Sabine has strong feelings about it. It's pandering. It's clickbait. Advertising and even payment consistently and inevitably causes the reduction of speech into drama and propaganda. Each KZreadr that engages in sponsorships falls into this trap and all their channels become hollow shells of their former glory. Honesty gets turned into drama. The depths are made shallow. The complex is made simple. The heartfelt is made insincere. The KZreadr clearly only shows up because it's their job. The passion fades and becomes jadedness. Lies creep in. Exaggeration bulldozes over subtlety. Truth dwindles. And the fanboys keep cheering. Like lemmings. Their brains rotted. Their faculties stunted. Off the cliff they go. I dare call out the BS for what it is. I despise Sabine for her fakeness. Another video only made so that there's a place to tack an ad onto.

This reminds me of cloud computing. I was a recent hire at a software company and inherited a project a recently leaving partner signed on. It seems he sold it to the clients by peppering the document with the word cloud with little to no actual meaning reflectig what the technology did. Instead, it appeared to be the cure all for every problem they had or could have. In the 5 page document specifying what our company would do, he had signed us up for a job that would have taken a team of experts years to do and me, a lowly junior, ended up as the lead developer with only three months left in the contract. Suffice to say, it did not turn out well and the term cloud computing always leaves a bad taste in my mouth. Seems that snake oil salesmen are making the same use out of Quantum technologies.

Back then, if you had a problem, just had to litter the term cloud into the conversation a few times and mamy would automatically think they new some great fix for almost any problem.

As a computing specialist myself I couldn't disagree with her more. An operation that's used heavily in AI, matrix multiplication, can be done on quantum computers. If a quantum computer is sufficiently scaled up, and these operations were run to train an AI, the amount of training on that AI you could do within a short period of time is ridiculous. This becomes increasingly important as data sets are getting bigger and bigger. I've sat around for hours waiting for a smaller model to train on traditional top end silicon hardware, imagine the bigger models. Quantum computers will revolutionise AI, and that's just one example. Quantum computers aren't going away, they're going to get better and better, and a bitter old lady who's mad that their obscure research isn't getting as much money as quantum computing won't stop it. There's hype but there's also substance there. Of course, it won't ever live up to the hype, no new tech does, but eventually it will exceed it. It's really unscientific to discourage quantum computers by saying it's a dead end.

There is commercial hype and then there is scientific hype. Don't confuse the two of them. Commercial hype about possible technological breakthroughs tend to inflate and collapse very easily. In 1822 Charles Babbage, the father of the computer, came up with a design for a mechanical computer that he called the difference engine. The English government funded him to make his design a reality but the metalworking technology at the time was too primitive. After 20 years the government gave up and considered the investment a complete failure. It wasn't until the invention of electronic circuits in the 20th century that computers exploded and became a part of everyday life. The theoretical possibilities of computers in 1822 looked just as promising as the theoretical promises of quantum computers look today. We may currently not have the technological sophistication to make quantum computers commercially profitable, but this should not deter us from pursuing further research and development into this fascinating technology.

I am so glad to hear someone else, someone with more credibility than I have, speak out about this. I've been dubious about quantum computing since the mid-90s. I'm not a physicist, but I've been doing software for many decades, and I've also worked with stochastic and probabilistic systems, and most of the time my understanding of the projections has veered off course as soon as the quantum jargon began to dominate the explanation. It always felt like hand-waving. I gave a talk at Interval where someone brought it up, and my reply (at the time) was "Yes, quantum computing will give you the right answer, and it will deliver it faster than conventional computing, but it will also deliver a multitude of wrong answers, so you'll have to go through them all to determine which one was correct."

I love your down-to-earth, rational explanations. And the humor makes it priceless. 😅 Thanks for sharing. Great video.

Thanks again Dr Hossenfelder ! A glorious mix of information and wicked wit!

Sabine, you are BRILLIANT . Thanks for your research.

Excellent. You have managed to bring together many aspects of quantum computing that I have been researching with much frustration. Thank-you

You nailed it! I worked in the supercomputer field, and spent time working with algorithms to solve quantum problems. I cannot see how the current quantum computer architectures can support any algorithms that compute, ab-initio, molecular structure.

I like Your humor woman. I like the links to free books too. I enjoy learning from You 🤠 Thanks!

Fascinating. Especially the factorisation of 21, and they had to make it simpler! Well I do think its impressive quantum computers can be built at all, but you really helped that bubble burst before it got any more big and dangerous. It seems to me that optical computers might be way better for most tasks. An optical transistor combined with the ability to compute multiply and add ops for neural networks in.a massively parallel way would be way more useful

yes even lcd, fluidics, 2d non dispersive non dissipative circuits, mabye graphene layers, or surface based , 2d logic gates are possible in 2 with accurate timers.. solitons, in 1d, advanced crystal nano fluids and such material sciences are more promising and show results. cheap and dont heat up nor need cooling. even a 8 cm wire has a massive voltage drop, these have no resistance so if they are bigger but flatter, and doent make 400 watts of heat, its great.

I have worked on systems since 1974 and I have serious doubts about the usefulness of quantum computers and I have had them since I first heard about it and I haven't seen anything that has given me more confidence in them. Hype is all it is.

I love your objectivity ( especially when it's pessimistic) as well as your humor! :)

Straight fire 🔥🔥🔥 Sabine you’re a real one 4 this☝️

This was super illuminating. I have watched about 10 to 15 youtube explanations of quantum computing, trying to find one that would give me a real world example of how it would do things better. Of course they mentioned pharmaceutical applications and other high-level things like that. But never a down to earth example that I could understand being a non-scientist. So Sabrina explain things perfectly, they have not figured out anything to do with quantum computing yet other than then to say things can be computed faster and then again only on a targeted limited set of problems with a super-small set of algorithims? Amazing, thx so muc Sabrina for cutting theough the hype!

Good Lord, do I love the snark from Sabine!!! This kind of reminds me of the hype behind the revival of 3-D and VR to be honest, and I suspect it'll pan out the same way: outside of specific applications its impractical at current tech levels. Unlike VR and 3-D (where the primary application is entertainment which chases the lowest common denominator), I think there are enough diverse applications for Quantum Computing for the tech to continue developing when the bubble pops.

I remember years ago when it was announced that scientists had built a device that could factor 15. Today I learned that they can now factor 21. I expect they will be able to factor 91 by the year 2030! Being able to cool things down to the millikelvin level with devices bought on the surplus market should open up some cool research opportunities.

AH a positive view on it I like it

Love, love, love, the quote gems sprinkled through your videos especially this one.

_"If you look at them, do they collapse?"_ I'm deeeefinitely borrowing this line. I was in stitches!

In a quantum winter you can know the air temperature or the wind speed to arbitrary precision at some point in space-time but never both, but either way you freeze.

Excellent summary. I wrote a paper, to spite Scott Aaronson, called "On the (Im)possibility of Scalable Quantum Computing." Would very much like your thoughts. Regarding algorithms, you mentioned the very short list, but the key one so often mentioned is Shor's Algorithm. Many have mistakenly claimed that this has already been implemented on a quantum computer to factorize the number 21, but this is patently false, which you discuss. Thank you so much for clarifying this, and for your great video.

There were some serious smackdowns in this video. Awesome content!

Everything you have s said so far makes mixed sense to me, my brain working on it . Your voice and those eyes can watch and listen forever❤

I always feel like the pursuit of quantum computing will teach us about edge cases related to quantum mechanics, some of which may provide fruit. After hearing your video, I feel like we should focus more on length of time staying coherent so we can at least play with the system. It's probably 20 years out along with fusion reactors and artificial general intelligence.

I spend the majority of my time teaching composition and music theory. And although I love my work, I often have this sense that I am using only one small portion of my brain. When I watch your videos Sabine, I always feel like these other dormant parts of my mind are being awakened and asked to stretch their muscles. I feel like I am being encouraged to venture beyond what I know and feel comfortable with, into this marvelous world that is so foreign to me in many ways, making it all the more wondrous and awe inspiring. I feel like an adventurer discovering new lands, and this is such a wonderful feeling! Thank you Sabine, for being my guide into this extraordinary uncharted territory.

It's because she is challenging a lot of the conventional wisdom. She is asking you to think for yourself, rather than regurgitate what you are being taught. Perhaps you can find ways to do that with your music. I suspect that unlike Sabine with all the BS surrounding physics, you will find a deeper understanding of the intricacies and realities of your field and grasp the wisdom of your predecessors, but finding out that the giants of old were right and understanding why in new ways is its own fun and equally challenging. But then again, maybe music theory has gone down the crapper, too, and needs the same kind of sanity to be brought back down to Earth.

Just as an FYI, the whole using a certain percentage of our brain is a myth. It helps to think of our neurons as a binary system like computers; neuron not firing as 0 and firing as 1. The 0 is doing just as much as the 1. It's obviously much more complex, but it helps illustrate the issue. If we used all neurons simultaneously, we would have a stroke BTW ;).

It did away with unnecessary components to make the switching occur (like heating elements, glass chambers, and a vacuum). I don't know that the hardware containing a fission process has changed much at all since it's inception (and ironically, it's still basically just a complex steam turbine engine), and fusion has never actually been used to power anything, (despite promises to the contrary for 30-40 years).

I don't believe there will be any change in hardware specifically determined by quantum computing. Quantum computing, provided it will indeed take off, will be very niche, and as such hardware will be developed very specifically for the things it's good at, leaving the rest of the hardware untouched.

Cloud computing because the idea of everyone having to supercool their personal computers or having a mini vacuum chamber installed is ridiculous. We're going back to the pre-PC days with quantum computing, but the benefits will be made available to the masses via the internet and cloud computing, and the IC technology which allows PC's the be small isn't going away.

@@shrimpflea Fission and fusion is not an apples and oranges comparison? If you want an apples to apples comparison, you'd want to compare between two different fission nuclear power plants. Fusion technology has not matured to where there is an industry standard, and an "apples to apples" comparison can be made between different approaches. I also don't like the term "apples and oranges", because it begs the question: when is it acceptable to compare two different fruit and why? Can you compare an apple to a pear or an orange to a lemon? What about a a red apple to a green apple? Do the apples being compared need to come from the same tree? What exactly are we comparing between the fruits? If we are discussing the evolutionary tree of apples and oranges and their common ancestor, THEN can we compare them?

My super-position on the subject is this: I favour a bit of quantum computing, but I try not to get too entangled with it.

I have been binging Sabines videos for 3 days straight

A follow up on this topic would be great. Because at this point, 5 Months after this video we have 433 Qbits Quantum Computer, Qiskit that can be used in combination with python and upcoming, the first prototype of a quantum software application. I don't understand the possible obstacles or limits of this technologie, but I can see progress. And we also have to remember that every major breakthrough was ridiculed at the beginning and many times called out to be impossible. I also would like to know what your approach would be? Wait until we could build a Q Computer right away with millions of QBits, Q-OS and Q-Software? Isn't research and experiments the best way to achieve ones goal and make progress?

Sabine is a good "grounding" factor for those with their head in the clouds.

This woman is a gift to intelligent people with a sense of humor everywhere.

Another fascinating dose of reality. Thanks so much !

A lot of us are sceptical and aware of how much hype there is, but, the entire grant system is based on promising future results and dreaming up how they create profit. If you are honest there will be no grant money for your research. It's a similar issue like impact factor that is more a measure of a field's popularity than actual quality of published articles. Science has been corrupted by capitalism and society at large has no tolerance for complex problems and explanations.

She's a physicist, clearly not a computer scientist to see the benefits of quantum computing. Matrix multiplication is used heavily in AI, and guess what can do that at ludicrous speeds? This physicist should stick to making science videos, not videos on computing she knows absolutely nothing about. Being an expert in one field clearly doesn't translate to anything. Of course, there is an initial hype phase of every new tech, but that eventually passes and then after that trough comes revolutionary tech. To say it's a bubble that's going to burst and nothing revolutionary will come out of it eventually, is complete bullshit.

So glad Sabine confirmed my vague understanding after glancing the content page of a Quantum Computing textbook.

You need to emote more. The delivery is on point. The scientific method is applied beautifully on your works.

Also, from an algorithmic standpoint it doesn't matter if an individual algorithm is of use or not. All algorithms fall into certain categories of complexity and approaches to solving them. There are only a handful of distinct approaches that are modified and repurposed for many use cases. If you, for instance, could find a way to solve sudoku puzzles in polynomial time, it would only take a matter of a few years to have several approaches for solving protein folding in polynomial time published.

In the early part of the 20th century, analog computers had the edge over digital ones in physical-simulation problems in being a lot faster, albeit with limited precision. I see history repeating itself, with “quantum” computers being the new-style analog computers. You never see them demonstrate any success with number-theoretic problems, for example, as would be needed for cracking encryption (what happened with Shor’s algorithm?). Just about all the success stories I hear about have to do with physical-simulation problems.

You are an amazing educator for beginners on this topic. I have taken this video to the topic on Quora. Thanks

great video for delivering mostly correct information. but I want to add comments on your short discussion on NV center and photonics. There are existing quantum computers already.

Bravo!!! Sabine, this may be my all-time fave of your video roasts (unless you do one that features my new theory and metatheory). I am even more inspired to expedite my practical alternative (to QCs), that improves equivalent "bandwidth" & security by nearly 3 orders of magnitude, while also improving E-efficiency by a similar factor. BTW, it also reduces the sizes of personal node units to a much more comfortable, affordable minimum. How? Briefly, a superior logic paradigm.

You are bloody fantastic , Nice to hear from a real scientist loved the comment about writing a book

The cooling for the ion trap quantum computers is a technical issue that might be solved. The main reason it is used is to decrease the pressure below 10^-12 Torr so that your ions don't get knocked around by background gas. Anyway - thanks for the great video!

Hossenfelder is getting better and better. At her very best she's producing biting sarcasm and it stands very well to her voice and personality. This is how science news necessarily must be to attract intelligent people. I'm not afraid to admit it, I love you Hossenfelder.

13:30 There was a very prominent astronomer who once said "We will never be able to know the chemical compositions of stars or interstellar clouds. His thinking was, the only way to know the chemical composition of something would be to analyze a sample of it. And he was probably correct in thinking we will never be able to take a sample of star stuff. But even when this scientist said this, spectroscopy had already been invented, though it was such a shot time after this that he likely had not heard of it. My point is, when a scientist says something will never be possible, they are very likely wrong.

I just found your channel. Love it!
