Some kind of UBI will be necessary, or there will be food and water riots...

I also think it will be more like 15 years. Before AI takes all of our jobs there's going to be a renaissance of new AI tools and "creators," making their own art and videogames and movies, all just by interacting with their "personal assistant."

That will wipe out 20–50 percent of white collar jobs within 10 years.

The robotics revolution, in conjunction with AI, will eventually erode the blue collar jobs. And that's when unemployment is going to get really bad.

The only people who will still be working will be "executives" and "politicians," and they will only be meat puppets.

Unless, of course, we do something about it heh

I agree, but who knows what the ethics of the ASI in charge will hold.

Hopefully, each "commune" has authority over itself (of course, that has its own ethical quandaries) and will create its own "constitution," or ruleset, ethics, ethos: anti-tech; technophiles; theiest; libertarian, etc. Probably a combination of ideologies that work for the collective and a level of technological integration (implants or no implants; internet or no internet; gene editing or no gene editing) which everyone agrees upon.

If this were the case, I guess each commune would also have the choice to choose whether to access the greater communities or jack into the FPG (Free Power Grid).

Long answer to your musing, basically: each commune will choose what level of involvement and education. Some might want to jack into free power and play in virtual reality forever, their children will be taught by virtual assistants and the community and will probably have very low muscle tissue. Others will want very little contact—maybe just a taste of free power—and want to create a farming community in the desert.

Education will be based on what is intrinsically important to each society.

Read it again. You seem to have misread my post.

That was the best case scenario that you identified. I didn't go into the worst case—I ended it with an ellipse (...)—because worst case AI futures have been waxed, written and illustrated for decades.

Yeah.

A future where they mostly subsist on UBI... and where AGI—both in virtual spaces (programmers, designers, writers) and in physical spaces via Atlas style robotics (construction and other laborious jobs)—will more or less do everything.

Best case scenario: humans of the future don't have to work. They will choose to make art, or play video games, or work wood, or build houses themselves. Life will become a Pusedonymous collection of communes that are propped up by AI and the humans within them do what they want because that's what they want to do!

Worst case scenario...
