Optimistic futurism is kinda the point of the channel, he even agreed that things could go very, very wrong and he does point out the possible dangers that could come from the implementation of various technologies.

I think that his optimism is refreshing, especially his episodes about life extension, artificial intelligence and transhumanism were top. Normally people either like to demonize it or go full Kurzweil, he takes a more grounded view andshows us possibilities how things could go right.

>>9779479
Good point

>>9779472
What are your favorite videos from him?

I think he's too optimistic about social structures and natural surveying taking place. Many of the huge populations he talks about would rapidly diverge and recolonize their ancestors in backscattering waves. Also, his very modern ideals of democracy would certainly never work in such a complex and high population future.

Of course that is not even getting into the problems of having post-scarcity economies would have on society. From a view of natural selection, it would certainly not be a Utopia, it would probably just grow in scale.

>>9779475
Arthur is obese tho

>>9779918
Yeah can you imagine quadrillions of people in a dyson swarm? Man that would be an absolute clusterfuck.

Cool channel, the whole laser highway concept is extremely interesting, using more or less existing tech to hit whatever % of c your ship can deal with is very impressive. Some cool ideas on how to shield ships like that too.

It definitely strikes me as the most plausible way to make an interplanetary ship if you lack some other propulsion method like antimatter or micro width black holes powered photon drives and don't want to deal with generation ships.

exactly. The only way that could be stable is if they were combined into a hive mind or hive minds, or all the groups of people are diverged and highly tribalistic, and the system as a whole is actively decentralized, like the holy Roman empire, or collapsing and falling apart. I don't know how long that could last though...

also if there are that many people, there is a certainty that there are many skilled malicious people, that will constantly work to change things. depending on how advanced the tech they have access to is, they could change things in a big way. (nanobots, plagues, von Neumann machines, nukes, antimatter, memetic attacks) This plus they increased fragility of any huge structures compared to planet Earth, I would be surprised if the average person had even the freedom we do now.

Again, that is a huge amount of people, so much that if the average person had any amount of influence, it would be possible to engineer memeplexes to make billions of people do anything. At that scale, any remotely Democratic system would be an absolute sham, and I highly doubt ANY system of government would be able to have enough layers and beuacracy that it could do anything. I don't even think it would be possible to be apolitical small units instead either, because the sheer complexity of so many other polities and people would be impossible to be kept track of by humans. Basically, people for not handle it, you would need specialized hypercomputers for it. And it would be highly autocratic to keep stability.

Did I mention again, the stability of a system of megastructures could be very very low, and said hypercomputer would have to, and be begged by the people to, keep the megastructure stable and running, as there are trillions of people in it. This effectivily means they are now forever stuck as slaves to the future technological system, as it is the only thing that could keep the megastructure stable, and them alive.

Pretty shallow for the most part. He pads it out a fair bit
>An O'Neill cylinder of 50 metre radius and 1 km long would have .314 square kilometres of area
>Double the radius to 100 metres, and the area doubles to .628 square kilometres
>Double it again to 200 metres, and the area doubles again to 1.256 square kilometres
And he keeps on like this. I mean, we get it Isaac.

>>9779475
I wonder if he ever deployed

>>9780903
btw here is an interesting pdf about making computing megastructures, it turns out waste heat and bandwidth are major problems
orionsarm.com/fm_store/Brains2.pdf

>>9780938
Probably because he's producing the videos for normies. He needs to hold them by the hand

>>9781045

>orions arm

Yiff in hell.

>>9781503
Orion's Arm is one of the best hard sci-fi setting because it incorporates everything, unfortunatly it also has stuff like furries tooo, but that's because a author thought them to be a novelty in the early 2000s. OA would be better if animal-human hybrids just wouldn't exist as their are outclassed by posthuman on all accounts.

stop talking about you know what and ignore it you ducking niggers. there's a lot of other stuff to talk about, there's not THAT much in it, very easy to avoid

Assuming that normal humans even exist and we won't all be some of super A.I/organic superhuman by then.

>>9781772
well yeah, can't theorize much about such an alien entity, let alone write stories with it as the protagonist

>>9781814
That's literally what isaac arthur does though.

>>9781826
he's pretty vague and overly optimistic about it

>>9781766
This, the vast majority 99% of it is very good, the pages about Toposophy, Wormholes, Magmatter, Emple-Doketikes and Autosentience are gold.

>>9781911
there are also a lot of really cool, Etsy I like to call, "life composed of strange materials" like magmatter life, natural von-neuman worlds, wind-grass computer simulator, CGoL, biological-computer von Neumanns, many different extreme biochemistries
there are lots of cool concepts and many in depth explorations into higher intelligences and simulated worlds and memetics

I might start a thread later and share a bunch of that cool stuff

>>9781956
The xenosophonts are always cool

Is it me or does the reliance on galaxy/star eating K2/3 civs sound stupid in the context of the Fermi paradox?

>>9782681
u r right. the availability of so many unused energy gradients is the universe is a big mystery, because after that is what life does. Grow and evolve to better equalize all gradients (heat, light, oxygen, carbon, nitrogen, water, trade goods, information). I highly doubt that if technological life is at all common in the universe, every single instance would go against the fundamental nature of life as universal engines. So either technological life is extremely rare, or there are other selection pressures we don't know about that steer life away from equalizing those gradients.

>>9779472
>even if I think that most of his ideas are bullshit and too optimistic
Absolute brainlet detected. We'll be able to do practically anything depicted in his videos (including megastructures) within a hundred years.

>>9783196
>within a hundred years

>>9779475
He needs to be strongfat

>>9780942
i think he did, he brought up setting up some optical equipment

>>9782681
Not just you. The assumptiom that every civilisation will develop Dyson spheres and the like seems a bit of a stretch. I know if I was in control of a star system, no one is building any dyson spheres or dismantling any planets or other rogue objects, fuck having hundreds of quadrillions of idiots running around the system and shitting up the views.

>>9783244
This. Just because you could theoretically build some of these infrastructures doesn't mean that you would need too.

>>9779472

Look up reusable rockets to see how much of a meme this guy can be sometimes.Nice for general concepts and visions of far future but typically for physicists the engineering reality is escaping him when talking about real technology and not space magic future tech

>>9779472
Better than watching Star Wars

LMFAO

>>9779472
He presents highly speculative ideas as if they were fact and often doesn't even acknowledge the existence of counter hypotheses.

I enjoy the videos for the detail in which he goes into popular sci-fi concepts, but I wouldn't put money on any of his visions being accurate predictions of the future.

>>9780942
Lol this guy knows more than einstein, sacrificed part of his life for the military army that keeps us all safe from evil, is handsome and also well spoken and people are still trying to nitpick eveidence agaisnt him not being a super man haha how jelly can you getter

>>9787009
>He presents highly speculative ideas as if they were fact and often doesn't even acknowledge the existence of counter hypotheses.
absolutely false, he presents every possible theory there is about everything clearly stating what is mathematically objective fact and which is his own opinion but masterfuly gliding amongst each one with perfect use of science, physics, moral, art poetry and writing. It is literally davinci of the XXI

The fermi paradox is about probability telling us the universe having to be swarmed with life and obviously not being.

The thing is, as Isaac himself has I think mentioned, that it doesn't matter if there are millions of civilizations that didn't expand into space, it would only take 1 civilization doing so for us to notice, and they would quickly dominate over the other ones, so the fact that we can't see traces of any civilization out there is a paradox.
