16:05 I might be a bit biased here, but as an ecologist I feel like the opposite solution is preferable, with Earth utilized as a nature preserve and more human cities and industry moving offworld into orbital habitats. Earth already has established ecosystems, and it seems like it would be easier to restore those than to create new ones whole cloth. Plus, I think there's a benefit in the continuity between deep past and present, which would be present on Earth but lacking in orbitals. This includes both the scientific (studying the history of life and how it operates within a planetary biosphere) as well as the aesthetic/cultural (such as finding a sense of wonder in the deep time history of an ecosystem, or people feeling as if Earth's nature is more "authentic" and orbital nature is more "artificial"). Naturally, I don't think they're mutually exclusive. You could certainly gain a lot of scientific and cultural benefits from creating nature preserves in the controlled, malleable conditions of an orbital. But I do hope that future civilizations of Earth do a better job of preserving its natural ecology than we have, for as long as our planet is habitable (and maybe longer, with the right astro/geoengineering hacks). Anyways, just my $0.02. Love your channel! Happy eight years!

I feel the same, but from a more historical perspective. The future Earth would make an awesome nature park/museum for all generations born elsewhere. Imagine all that tourism revenue! Plus, the living planet from low orbit might just be the most spectacular view in the universe (at least until/if we find alien life).

Strongly agree. I just like to present this more as a long-term study. Earth is the only place in existence with hosts a complex life that we know of. And it is an ever-changing system. Preserving ecologies is fine and dandy, but I see Earth as the only real "bioreactor". It would be a waste to not see how life evolves and diverge without human presence. Altrough not necessary without human intervention. I see arguments for preventing mass-extinction events and supplying desserts with resources for life. Like vertical reefs (basically big ocean towers providing light and nutrients in barren stretches of water), Isaac came up with back in Earth 2.0 series. Fascinating concept.

Here’s the problem with your statement, though. Established ecosystems change, so if anything we should seek to be the “Tiger” ie cultivate the ecosystem around us so that we can have our cake and eat it. Basically, I’m saying we should learn to make Ghibli worlds and embrace Solarpunk practices instead of the very Cyberpunk direction we seem to always head for. Everything he says just makes it sound like we’re headed for the Expanse in the next few centuries, but they can very easily be remedied with a more solarpunk direction.

​@@KRYMauL To clarify, I wasn't meaning to suggest that we keep Earth's ecosystems in unchanging stasis. Nor was I trying to suggest that _all_ humans move off Earth to take a completely hands-off approach. I'd personally be _totally down_ for a more solarpunk/Ghibli-esque style of civilization on Earth that exists in much greater harmony with natural ecosystems. I've actually dabbled a little in solarpunk writing myself and like the concept and aesthetic a lot. That said, I don't think this is mutually exclusive with moving out into space or even developing more "cyberpunk" style civilization components. Arcologies, orbital habitats, and distant mining colonies don't _have_ to look like the grim, gritty, noir-esque settings beloved of cyberpunk writers. An orbital habitat _could_ be a lush conifer forest, an arcology _could_ be woven full of parks and greenbelts, a distant mining outpost _could_ have tons of gardens with fresh veggies. It's just a matter of getting the right technological possibilities to line up with the right social incentives... which is kind of just the same problem as on Earth. Plus, building an orbital ring and hanging things off of it seems like a pretty effective way to build a _literal_ Castle in the Sky!

Then there are the people who say "green energy no matter what" and reject nuclear power because they've watched too many movies and the Simpsons (how are you doing dear californians). And definitely not last nor least, the people who want humans to stop having children to help ease climate change, clearly not a smart bunch. The best course of action is to make personal sacrifices and try to help/come out with research and new ways of being able to control our climate. I still remember how we were supposed to be drowning 10 years ago, or the many many other worldwide failed predictions and alerts.

Another fantastic episode. Subscriber for 5 years. Happy 8th channel anniversary and 42nd birthday! 2:30 - I think that was intended to look like a face? Maybe resemble 'the face of New Sidonia', perhaps? On Life Extension, Enhanced Fertility, population density/scattering and population growth: There are sociological considerations and ramifications when talking about changing how often and how long an intelligent species reproduces. Scarcity/abundance of resources and space affect people's ability, opportunities, and inclinations to produce and responsibly raise new members of the species and the civilization. I don't see any but the most decadently affluent individuals or family groups clamouring for their own habitable space structure. I once did a rough calculation for myself, and found that at the current population of America, there is enough land area in the continental U.S. for every single individual to have an acre to themselves, with nearly two-thirds remaining (for agriculture, industry, land preservation & conservation, & c.). Granted if life extension becomes a reality in this century then the demands of the human population on the ecosystem will grow, but with advances in other areas such as power grid engineering (we are already seeing this develop today), multifunction structures (i.e. Arcologies, great video BTW), and material handling and recycling, such constraints will likely be widened considerably ahead of population pressures. The main idea that I wanted to mention though is socialization. If family units become more spread out and isolated, the opportunities to interact with other family units on a day-to-day social level and become acquainted, friendly, and cooperative goes down precipitously. For this reason I do not think that fertility enhancement (except to aid those who want a natural, biological family and are told 'no' by some medical obstacle) will necessarily have a positive sociological impact. If people can wait for three, four, five decades or more to have children, and potentially become isolated, fearful, suspicious, and narcissistic, then they are much more likely to pass on these values and behaviors to their children, who will be more likely to do the same. This would result in some family units having not necessarly more kids, but around the same number, and later or more spread out across historical time. This may have its own advantages, but it would also throttle the populational growth rate. 'On the other hand' [as Tevya would say], people with an early, limited window to have a biological family may or may not do so, just as they do now. I'd like to believe that society and technology would incentivize the activity (as I believe it is both socially and morally healthy to raise a family before personal pursuits), but at the same time, there is the difficulty that in the 21st century - at least in the west - many younger people tend to value freedom, independence, and 'unattachment' to social and familial responsibility. There are different views on whether this is beneficial or detrimental; my own view is that there is a limited sociological window for authentic family attachment, before an individual becomes so preoccupied with their own interests and self-improvement, that family life ceases to appeal or 'call' to them, and so they contribute to future generations intellectually, aesthetically and/or socially, but not necessarily genetically and familially in terms of population. The last thing I will consider on this topic is the matter of polygenerational families, something that only occurs in Biblical accounts, and is not known by civilizations of the past or present. This is not something I feel completely free to speculate on, because it is a psychological and sociological unknown. But life extension to 100+ years, potentially to 200 years or more, makes this a definite possibility. I read one fantasy series that touched on this subject more deeply than Tolkien did with his Elves who lived for centuries, and the author (Christopher Paolini, the _Inheritance_ series) brought up two things about his own elven race: 1. They were careful to observe courtesy and protocol, regardless of their personal affectations toward other individuals 2. They were extraordinarily studied and subtle in their behavior and interactions; a single gesture could be part of a machination or stratagem spanning years or decades. These are, of course, the author's inventive inferences, and are not necessarily more valid than mine. I would like to think that life extension, particularly in the absence of a widened natural fertility window (for neither males nor females), would create incentive to become more mature and socially responsible more quickly, rather than the poet's line quoted by St. Paul "eat, drink, and be merry, for tomorrow we die." If anything, the tumult and upheaval of the last two decades has taught us that what we need to continue advancing in scale in maturity, not just technology, is more citizens - people of insight, foresight, courage, and responsibility - and less celebrity and political train wrecks.

I'm definitely in favor of garden parks and nature preserves in between urban arcologies with agriculture belts around them. Of course, we'll need to do lots of recycling and pollution clean-up to get to that stage, and any resource extraction will probably be off planet. But it will be an idyllic way to live, I expect. BTW, it would be cool to use "star lifting" technology to get materials from the Sun, and lower the Sun's classification into the K range, thus extending its life to about 30 billion years instead of 5-6 billion. That would put Venus into the Goldilocks zone, too, as well as giving us the resources for grand megastructures.

LOVE this channel. Thank you Isaac for your incredible imagination and ideas.

The Makarios Scale of Technological Development is a revision of the old Kardashev scale. Look at these: Type One: "Novice" (revised) intensive use of more than half of the planet's habitable surface area for urban dwelling, agricultural production, industry or resource extractive purposes. Oceans, ice caps and deserts are not typically considered habitable, although some oases may exist. Type Two: "Unstable" (revised) threatening the ecological health of the planet by careless practices, whether by stripping resources, excessive pollution, or loss of secondary species. Type Three: "Emergent" (revised) has acquired sufficient technology to make space flight and colonial ventures possible. Potential for mass self-destruction demands a quest for coexistence. Type Four: "Maximized" (original) Type One: intentional use of all the insolation received by the planet for food or power. (revised) has accessed or made feasible all of the resources and energy available on the planet. Approaching a sustainable global regime for shared resources and political consensus or a tolerant balance of powers. Type Five: "Outbreak" (revised) has established self-sufficient populations, with trade routes, in multiple extra-planetary colonies, and continuing to spread. Industrial development of free-floating habitats, space infrastructure and specialized project construction begins. Type Six: "Established" (revised) has explored the entire stellar system in sufficient detail to map a super-majority of its geography and resources. Technological proficiency allows pioneers to colonize the frontiers at will, and choose political independence. Type Seven: "Expansive" (original) Type Two: intentional use of all of the energy output of the star for habitation and industrial purposes. (revised) complete access to all of the resources and energy available within the star system, including its planets, moons, and smaller satellites. Experimental robotic ships explore the nearer neighboring star systems and the conditions of intermediate space. Type Eight: "Arrival" (revised) first colonies established around other star systems. Ultrahigh-energy physics experiments explore the potential for travel at relativistic or supra-lightspeed velocities. Type Nine: "Manifesto" (revised) seeding the stellar neighborhood with many colonial ventures, discovering the range of variety of system formation and geography, and revealing the frequency of the origins of life. Type Ten: "Epitome" (original) Type Three: acquisition and use of the entire energy output of all of the stars in the whole galaxy. (revised) technological capacity to range at will throughout the galaxy, planting colonies, developing resources and tapping unlimited energy as needed to sustain the presence and growth of the species in all its various iterations. Sophisticated modes of long distance travel and self-contained habitat ships allow for sporadic attempts to surpass galactic boundaries. Conclusion: As you can see, the original version of the Kardashev scale assessing the power use of a space-faring civilization was excessively over-simplified. Having only three tiers, it did not allow for any detail or description of the intermediate stages of development. At every stage, it required an "all or nothing" obvious achievement in order to advance to the next rung of the ladder, and totally lacked any descriptive or predictive powers. This revised version does have more capacity for descriptions, and also allows for a certain amount of flexibility. It can be used to note and measure some fractional attainments, and can accept some skipping and mixing of non-linear development patterns, while still offering some definite levels of meaningful achievement for comparisons.

Love these channels! Thanks for the awesome & informative videos! 🔋🪫 ☀️ 🌎

This channel is awesome, keep it up.

Oh, wow. I can't believe it has been 8 years! I think I found you about six years ago and spent a long time trying to figure out where you were from because of your sexy accent. I think I finally decided you were Korean. haha It has been a genuine pleasure to watch this channel grow, and to see it become what it is. Take care, and keep living the dream! :)

Happy anniversary dude

How could your lucky number *not* be 42 ? Happy Birthday, and Happy Anniversary. :-) Thanks for all the fish.

Thanks Isaac, always appreciated.

I have been a little pessimistic about evolution leaving much of any low-hanging longevity fruit to be picked in already long-lived species. So I was thinking we were going to need absolutely comprehensive repair of tissues at best, or at worst, a thorough understanding of metabolism, with all its eye-watering, despair-inducing complexity. But of late I'm thinking there probably really are some near-term, relatively simple measures that can be taken. First, *_we now know how to rejuvenate the thymus._* This is huge. A youthful immune system solves a lot of problems. Major clinical trials can't begin soon enough. Also, there is this idea, _antagonistic pleiotropy_ -- genes that increase your chances of reproductive success in early life, can have very negative effects in later life. Kin selection effects notwithstanding (e.g., the proposed grandmother effect, where longevity is selected for via grandmothers contributing to the reproductive success of their closely related grandchildren), evolution doesn't give a damn about post-reproductive periods, so genes that harm you in your old age are not much selected against, and in fact they can be selected _for._ So major progress may be made by simply silencing certain genes in later life. And our technology to accomplish that silencing has advanced extremely rapidly in the last 15 years. One especially exciting current effort at targeting multiple diseases of aging via gene therapies is Prof. George Church's _Rejuvenate Bio_ company. They will bootstrap to human clinical trials by developing treatments for dogs. Monied dog-lovers (among whom I count myself ... well, at least the dog-loving part) will spend big money to have healthy, energetic 17+-year-old dogs. And because dogs are much better analogs for humans than rodents are, in many ways, in terms of diseases of aging (dogs fail in old age in ways very similar to humans), funds from the pet business can go towards human clinical trials for the same, or very close to the same, gene therapies. It may be that these approaches only get us to people being healthy and vigorous up to about 115, then going downhill rapidly after that. But that's a _huge_ improvement -- and it may buy us all enough time to be around for the truly comprehensive rejuvenation technologies. Unfortunately I think we are going to have various longevity technologies (that actually work) for a couple decades before they are widely available, at least in the USA. The most important thing anyone can do is prepare to be in decent health 20 years from now.

Without major reform to Social Security and Medicare and similar programs outside the US, I would be concerned about suppression of life-extension technology except for a connected few.

can't watch anymore of your videos, my brain hurts... but I appreciate you. I just liked the video for the algorithm... keep up the good work

I propose a new scale where efficiency is the priority. The civilization starts by using a entire galaxy of energy and slowly reduces this to a 9v battery gathered from Hawking radiation. All the while maintaining the same level of complexity and population.

Happy Birthday IA

Nine years.. It really don’t seem that long at all. I suppose it is a case of “time flies when having fun.” Thanks Arthur and everyone who contributes ❤🎉
