AI is not important at all. Just make things more convenient, but is completely unnecessary.
Check back in 5 years. This is going to age poorly. The reason is that, despite what many think, AI actually is able to create novel ideas and solutions. That's why AlphaGo was so important; it couldn't beat the world's best Go player just be being a fancy autocomplete and a big processor. It had to create new discoveries and then use them effectively. That was the turning point. It's been a decade of improvements si…
In no timeline nor carbon-based universe does GP's comment age poorly.

I am a bit skeptical but cautiously optimistic about AI “creating novel ideas”, if we are using “create” pedantically. Any interesting examples?

#54Life began in the Ocean, but why did civilization begin on land? Is it because of fire? But I wonder if a different kind of civilization could have emerged
Can’t answer that, nobody will likely to be able to ever, outside religions. We are NBKs. How that happened, idk, some cosmic curse. Dolphins didn’t develop atlatals, broad heads, catapults, napalm, and F35s.

Those math proofs from a few weeks back seem plausible.

#56Earth made water.. right.. and a big explosion made the earth? How stupid do you think we all are?
How could the Earth be round? All the water would fall right off!
Re: Where Did Earth Get Its Oceans? Maybe It Made Them Itself
#57"Other scientists agree that some amount of water could have formed on Earth — but perhaps not nearly enough to produce its oceans." "Earth might have been a water factory for only a moment, but that moment may have been enough to forge oceans."
Well, our planet has magnetosphere and it also had life for a long time already. Although the magnetosphere reduces the influx of Hydrogen in form of solar wind proton bombardment, it also prevents the loss of Hydrogen that managed to get captured on Earth by not letting it be blown away from the upper layers of atmosphere. Life at one point, almost two and a half billion years ago, caused the Great Oxygenation Event, in which the entire atmosphere got Oxygen rich. This very special atmosphere (for all that time) made it possible for the incoming Hydrogen (be it from the Sun, other stars, or just as the most common form of dust in the universe blown in here from whatever direction and cause) to ultimately be collected as water. Two and a half billion years, that's a lot of time to accrue water. It ought to show, at some point. So it's at least one pair of factors that could have led to a surplus of water we see today, besides what might have existed from very beginning.

#58I've read Europa has more water than Earth. Is the idea that it accumulated its water through an entirely different means? Or that it formed with its water, and didn't lose it during the initial coalescence, like the Earth did?
This is one of those areas where I don't know enough to oppose the scientists that are experts in this domain, and so I know I should accept the general consensus... but there's still a niggling doubt in my mind because it just doesn't feel right.

That's one theory, yes. Cooking food (with fire) makes more calories available, meaning less hunting required to support more individuals, and/or freeing up more time and calories for thinking. This allowed us to evolve bigger and more complex brains. While it's not a given that fire is a hard prerequisite for an industrial civilization, it certainly accelerated our technological development. Fact of the matter is, w…
Fire, agriculture, electricity, AI. Rank these inventions in terms of importance to humanity.
AI hasn’t taken its final form yet.

#60Earth inherited water, released it, and retained it, while the atmosphere and oceans formed together as a coupled system. Heating released water via volcanism. Outgassing formed an atmosphere rich in water vapor. Cooling caused condensation and rainfall. Oceans stabilized.
Oxygen accumulated only after oceans already existed for over a billion years.
