> The issue is there isn't enough of those small environmental economies to support everyone that exists today without the technology, logistics and trades that are in place today.

I agree. I expect some parts of the world will see some black days. Lots of infrastructure will be gone or unsuited to people. On top of that, the cultural damage could become very debilitating, with people not knowing how to do X, Y and Z without the AIs. At least for a time. Casualties may mount.

> Also humans (especially large groups of them) need more than food: shelter, clothes, medicine, entertainment, education, religion, justice, law, etc.

This is true, but parts of the world survive today with very little of any of that. And for some of those things that you mention: shelter, education, religion, justice, and even some form of law enforcement, all that is needed is humans willing to work together.

> all that is needed is humans willing to work together

Maybe, but those things are also needed to enable humans to work together
