“Completing” technology would be an an exponentially bigger task than completing science. Complete science is knowing everything about everything that actually exists. Complete technology would be knowing all the ways to arrange the things that exist into things that COULD exist. One is analogous to knowing all 52 cards in the deck, the other to knowing all 52! (8x10^67) ways to arrange the deck.

Thinking that they reached the end of fundamental research is a bit of an idiosyncrasy of theoretical physicists (and Isaac is one at heart ), let's remember when, at the end of 1800s, they were sure their job was soon to be over, once a couple of pernicious problems got solved. Of course, the remaining issues were black body spectra and reconciliating Maxwell's electromagnetism with Newtonian mechanics, but clearly it was going to be some small work.

One barrier to the "completion" of science is the locality of data. Everything might be known, but it could never be known by *everyone* simultaneously, whether you are considering people or entire civilizations. As the near-infinite mountain of mixed junk and valid information grows, it may often be more efficient to independently re-discover something locally than to sort through it to learn what someone else previously discovered

[@maddockemerson4603]

I was going to comment something along those lines. I can easily imagine a future in which people take up science, even though there’s nothing new to be discovered, so that they can be reasonably certain in their knowledge and well-defended against nonsense.

What if in the future all knowledge is in some database or distributed on the internet and whenever your brain tries to think of a fact or thinks of something that might be relevant to a fact, a chip in the brain communicates with the database or queries the internet and the facts are recalled by the individual.

In theory, every PhD has contributed something to their field of study in order to get that PhD. Most people I know with PhDs have contributed a very real, but thin sliver of knowledge to their field. I can imagine PhD candidates continually measuring the speed of light to greater precision or examining the energy of the OH bond in some specific alcohol. Kepler discovered that planets have elliptical orbits when he was trying to support the circular orbits of Copernicus, which was a simplification of Ptolemaic orbits, using Tycho Brahe's astronomical data, which was better data than previous astronomers had made. Given that such monumental discoveries can be made by building on such incremental developments, I could only believe in the end of science if you first dried up the supply of PhD candidates.

As long as a species has individual members who seek use mind altering substances, there is always new things to discover. Epiphanies happen on drugs all the time, people have accidents that change our understanding of things, people think "I wonder if drinking/eating/smoking that will get me high" about random substances if they're bored enough, and I think we all know someone at some point who said "you what would be cool..." after ingesting some substances which could have led all sorts of ways from debate to experiments ending in medical discoveries or knowing our own limitations. I could see an end to science, but that would potentially be the most boring thing ever because then creativity is likely gone. And I too fear a Dystopia where causing suffering as a lifestyle or everyone being an addict as a potential problem of those types of post science civilizations just getting bored. I've always been an optimist with post scarcity civilizations and I'd like to believe many people would find new crafts or hobbies to learn to physically master if given free reign of their lives because their basic needs are all provided them. And yes you'd have people creating the same type, maybe even the same model of craftsmanship, but it bares the marks of that craftsman and it wouldn't ever be exactly identical especially with wood or stone work with different grains or knots making their own unique patterns.

Recreational drugs often leave people feeling they have had an insight. Rarely is it an insight that is empirically tested and found true, and insightful by others. I suspect a lot of this phenomena may involve the drugs making any old idea seem insightful. Imagine a definitive neurophycology paper, that told you, given any chemical, if it will get you high. There is a piece of software that calculates this from the chemical name. All the chemicals found in nature have already had this computed, and it is standard practice to compute it whenever synthesizing anything new. (Because you need a license to synthesize psychedelics, say) Suppose science is done. People still make art. People still design elaborate and somewhat pointless technological artifacts. A bunch of people put a lot of work into a machine that turned frozen bread into frozen toast without defrosting it.

Also what I call "happy accidents" like discovering penicillin, or discovering targeted radiation can work as a treatment against cancer, someone just made a mistake but because something unexpected happened you see if you can replicate it. I get the need for tinkering, but if you're creating something unique that hasn't been done before then that's actually in a way a scientific discovery.

Yeah its always the case that biases are important to how we frame our current understanding. In particular one assumption which is regularly made but appears to be problematic is the assumed validity of the cosmological principal, i.e. the assumption that there is some scale at which space becomes effectively homogenous. The No big crunch theorem proved by Matthew Kleban and Leonardo Senatore in Inhomogeneous and anisotropic cosmology (iopscience.iop.org/article/10.1088/1475-7516/2016/10/022/meta) effectively shows that at least in the case of any nontrivial universe approaching the limit of infinity that some of the key aspects of the cosmological principal such as the idea that the terms within the metric tensor can ever cancel each other out will always either break logical internal consistency(i.e. information is not conserved) and or causality. The natural resolution to this liar paradox analog is that no two points in spacetime can ever be the same i.e. It is either the case that information and or causality are broken globally or all possible points in spacetime must have a unique metric and there is a nonzero minimum component of gravity for each and everything within the Universe even those beyond the cosmological event horizon. Or equivalently this is effectively the same kind of reasoning why energy states must be quantized suggesting that this implicitly does mean space is naturally quantized and more importantly nonlocal with the universal constraint on the metric surprisingly turning out to be a volumetric formulation of the second law of thermodynamics as for any initially expanding universe it can be proved that no possible valid states can exist which permit such a universe to start contracting. (In this case if we think in terms of information you can think of the metric in this limit as the sum of all casually possible pair interactions which naturally leads to Bell's inequality and ER=EPR This is obviously simplified but the point is that the cosmological principal assumption can easily be falsified by a simple metamathematical analysis by proof by contradiction where you show that for such a solution to exist it must demonstrate two mutually incompatible properties. I find it surprising that no one ever checked for the metamathematical properties needed for any solution to be part of the set of all possible valid solutions to the Einstein field equations but as the founder for the metamathematical formulation was only born in 1906 Einstein gets a pass.

Biological evolution is doing that for billions of years and we are faster and much less coincidence-based than evolution, but our technological evolution that consists of cycles of research, development and reflection will probably still last a while. Maybe we will reach a point where expanding in size makes no sense or at least yields no profit, and we will instead expand into the smaller scales, making everything smaller and more efficient, including ourselves, until we hit the hard Planck limits of the quantum resolution of the universe. That would be a new tree of exploration and development that could give us a few more millenia of progress and curiosity. Maybe that would make us smaller than an ant but at least as intelligent as today, in turn freeing up massive capacities to do new research in the larger or growing scale.

The content is always amazing. It really gets you thinking about what could be.

[@bilbo_gamers6417]

imagine an alchemical sort of science fiction story set during the time of isaac newton, in which light was just a particle and not a wave, gravity was a force, there was no quantum mechanics, no nuclear fusion, certain objects such as stars just emitted heat infinitely depending on their mass, and the speed of light was infinite. insanely simple totally mechanical universe with no mind bending nonsense going on. space ships operated on the principle of using vacuum balloons, which could float into space on the aether that surrounds everything in the spaces between the planets.

[@cacogenicist]

I can image a state of affairs where the universe is fully understood, fundamentally -- but where you could still spend a very long time working to understand large-scale, complex dynamic systems. And -- related to the previous point -- I think advancements in engineering could go on long, long after a civilization is no longer making much progress in fundamental science. Science and engineering shouldn't be _too_ tightly coupled. In other words, 1 million-year-old *Civilization X* and 100 million-year-old *Civilization Y* might have the same level of fundamental scientific understanding, but I believe that *Civilization Y* could be wildly far ahead of *Civ X* in technological capability and achievement.

[@ArticBlueFox96]

A post science civilization feels like what happened to the Q Conitnuum of Star Trek, where the Q have effectively experienced everything and done everything and experience and done everything so many times that they have grown bored of everything, of course for them it went beyond scientific knowledge and was all possible experiences. If we become immortal, the value is that things don't end you just move on to the next thing, but if we ever reach that point where everything has been done then things have ended. Complete immortality therefore would require a never-ending supply of new things to experience or learn or do. A very interesting topic, thorough in presentation, and thought provoking video as always. I am looking forward to your upcoming episodes, especially the Grabby Aliens (which I have seen a lot of people talk about lately). If you are ever looking for more topics to consider, some I would suggest are: * Returning to some old topics with a new spin or update, like life extension or anti-aging or brain-computer interfaces and VR, etc... * Looking at some of the new future tech that we may see in the short-term (a matter a just a few years or decades) * AI drug discovery and AI scientists and AI engineers and inventors/innovators * Robotic social and sexual relationships with humans or the non-human or semi-human descendants of today's humans

[@theeyeofomnipotent]

A temporary solution is to forget non-critical memories that is associated with entertainment, with it you can enjoy things repeatedly, although it might lead to some existential crisis lol, If humans are immortal now, it would actually be kinda alright, as human memories are like what i mention, not fully precise and permanent Of course the true solution is new creation, "they've grown bored of their finite multiverse, so they made it infinite" < paraphrased from downstreamers, To have an immortal is to be a civilization worthy of an immortal :3

[@PhilipMurphy8Extra]

I don't think science would ever end but 3 is what is likely in my head to happen, Judging by most other people I am not sure if they will understand that much new science. So if it happens if could turn into a niche hobby for few people.

[@simonpetrikov3992]

I think my most likely prediction in regards to the end of science topic is that it eventually it would take as long as the Roman Empire has existed to make a breakthrough unlike today which can take decades at the longest Note: the Roman Empire lasted 1480 years That’s the equivalent of a making a breakthrough in field of research that was started in 542

[@psnetdistribution]

Science as the act of observation and measurement can never be complete because there is more to the universe than we can observe and measure.

[@astroZ45]

The premise here reminds me of the director of the US patent office who recommended closing the department because everything had already been invented…in the mid-1800’s.

[@rmeddy]

This is a really cool one. You can get into all kind of interesting philosophical rabbit holes about the concept of completeness. Ideas of demarcation, consillience and commensurability underdetermination for how future. societies may address these debates.

[@marcossonicracer]

tbh im optimistic that we would just make Clarktech look like child's play in the future if we discover tips and tricks on the road. i mean if we already theorized something like an Alcubierre drive or how to transform the human body in any shape the user of it wants to... then i guess it will be possible one day to just surpass these barriers if we put enough effort. after all, isn't the first rule of warfare the one that goes like: "if you're not puting enough power on something, you're not doing it right. There isn't Overkill"?! XD

[@richardgreen7225]

Another limit might be how much knowledge a human brain can process in a lifetime. On the other hand, an artilect that thinks a million times faster than a human might hit an 'insufficient data' state very quickly and have to wait while data gathering equipment is built and gathers sufficient data ... to overcome the 'insufficient data' hurdle. Once the artilect has learned everything that (currently) can be known, asking it a question might trigger the response: 'You lack the necessary capacity.'

[@Cythil]

Even if science were to be completed, other fields are pretty much limitless. Mathematics has no limits. You can always find something more to do in that field. Of course, it may not have the ability to holds people interested in it. Especially if you move more towards the more esoteric kind of math that seem to have no practical use at all. But still not limit. But there might by a real limit to how much we can understand math. Simply the limits of the universe (if there is some) could conspired to how vast of a mind one could develop to understand the field.

[@CJusticeHappen21]

I totally wasn't expecting the 40k twist in the speculation. I appreciate it.

Try answering the collatz conjecture. And questions like that become physics questions when you can find or imagine a physical system that works like that. Try understanding everything, good luck with your quest.

[@williammcclellan3497]

Thanks to Isaac Arthur I got to watch this on my 67th birthday and in reflection I realize that being 66 means I've slept 22 years of it away...

[@jamesasimmons]

Honestly our biggest barrier is the limits of our minds. Personally I think we hit that limit sometime in the 80s or 90s. Thankfully computers have stepped in and pushed us forward.

[@TheExileFox]

But also backwards. Lots of software is eating so much resources without needing to. See the memes/jokes about Chrome and RAM as an example. Optimisation has been thrown out the window for years now. Instead more power is thrown at the problem because it seems easier.

Great video! Thank you for making it

[@DerGrinch88]

@16:25 you said people from 1000-2000year but if you look at people of 800 and 1800 then the difference drop a lot i think our technical evolution trough the last 100~200 years are far faster than in the past that could have a lot of different reasons but in comparison to the universal age we are just short moment,we have so much more to discover, find and observe out there foe example black holes, maybe white holes and in the long run the multivers or even higher dimensions, that i think there will be no end for science more like a deadend where we cant overcome till new experiments are possible and so and on. there is the theorem of the unknown we don't know what we don't know till we know or at least ha a clue what is missing. You are making awesome videos i really like

[@davidweihe6052]

It may be possible to run out of learnable information. Due to the expansion of the Universe, there are galaxies that recede so fast that, while we once could see them, we no longer can. Eventually, the information that has receded may be vital to decide questions previously askable. When the visible Universe has shrunk to the Local Group of galaxies, any questions larger than that will be undecideable.

Personally, I kinda suspect that, once we become intelligent enough to model the entirety of creation and predict everything, there will be nothing left to know/explore and hence the ultimate great filter.

[@DeSpaceFairy]

The type of post science civilization I found the less likely, is the one that we collectively decide to not go further because this obviously dangerous. That because it has to be assumed we got one homogeneous civilization, sharing the same ideas and no entities competing with one another for whatever reason, even having passed post scarcity.(Or unlikely as long we are the same psychologically speaking.)

Heat death is inevitable; when death is certain, it is foolish to stagnate out of fear of the inevitable coming sooner. Pursue the heights of experience.

I am reminded of the 1900 belief that 'science was complete' with Newton's Laws, Maxwell's Laws, Thermodynamics, Chemistry, and Evolution all 'well understood' ... Only a combinatorial explosion of possible configurations remained to be explored.

[@donaldduck7628]

One thing, every 20 or so years, there is a whole group of people that have the whole body of science as something that is new. There is a whole effort to refine existing class of science to deeper levels of precision.

[@Dragrath1]

One problem with the idea that you may run out of science is Gödel's incompleteness theorem shows there is always some rule which is true and no able to be proven within a axiomatic system. In this context on option 3 is permitted in the basis of axiomatic systems. Technically free will *is* an illusion caused by the sheer chaos of our universe and frankly our brains reactive processing and retroactive justification is naturally hidden by how we perceive our world. In the case of biology its currently undergoing major revolution due to molecular biology improvements which discounts the claim that its largely the same as when Einstein was around. We have even found entire organs that go missed in humans.

I agree I feel like after science there would still be scientists but they’d be like science artists or science artificers, making incredible things using science or to visually display some rule(s) of the universe, it’s gonna be great

I fear a post-Isaac future, where there are no more topics to be covered. No new videos to be made.

[@lukasmakarios4998]

An end to discovery? How would you know that you know everything there is to know? There might be something left to discover. What happens if you find a new problem, or an unseen application? The emergence of existential apathy or ennui, however, on the presumption that there isn't anything more worth discovering could be a problem no one is trying to solve. Think of Arthur C. Clarke's "City at the Edge of Forever" for an example.

[@xXx_Regulus_xXx]

I imagine there's probably some threshold where if you go n number of years without a new discovery and every phenomenon you encounter in the universe is explainable by known science, even if from an objective viewpoint there was something we wouldn't discover for many generations or flat-out would not be capable of encountering for some reason, we would think we were post science and probably not without decent reason to think so. I like to imagine even at that point there would still be a faction devoted to doing endless replicaton studies, _just in case._

[@samuelharbison676]

Any idea why captions aren't available for this one? While he is not difficult to understand, I enjoy having captions with all my videos.

[@marlonlacert8133]

In the 1800's a young man's suicide note read something like this: "Due to that all things in science have already been discovered, I have nothing more to live for!" His university teacher was telling all students that science was complete. "Everything that can be discovered, has already been discovered! And there is nothing new left to find!".. Boy, was he WRONG! Turns out science had just bumped into a block! Our science may once again hit such a blockade.. And we may remain stuck for 1,000's of years! It may then take a so called FOOL, or a discovery of an lost civilisation that went a different way.

I don't think we'll ever run out of science. There seem to be an infinite number of patterns to discover just in the set of natural numbers. If you've been following Numberphile for the last decade you'll know exactly what I mean. Prime numbers, perfect numbers, triangle numbers, square numbers, Pythagorean triplets, the list goes on and on. And that's just the most basic math we can do.

[@RiversJ]

And pray tell what will you do with proper research mathematicians once someone invents a generalized mathematical computer that can synthesize any and every optimal solution for every problem you can imagine? I'm not being facetious here either, it's the most probable "future tech" we are likely to invent, far before we get AGI or widespread safe fusion even, in the form of self-retraining quantum neural nets.

[@feynstein1004]

@@RiversJ That's a different story. I said we'd never run out of math, not job security for mathematicians 😂

[@justsomeguywashwd_jbm821]

It's 1 thing to discover the laws of science, but that doesn't account for the potential applications of that science. Innovation often comes about after someone has an idea to apply 1 or more known things in ways that nobody else has before.
