Sure. But not everyone can be doing that for money.

No it is like horses 1750. Horse couldn't imagine all the jobs there will be in 2020. Only thing is that those jobs weren't available to horses but humans. In our case in future all new jobs will be available mainly only to AI.

>I don't oppose AI but I think we'll need to find alternative ways to satisfy the needs of achievement, self improvement and social value. We could have infinite food, housing, entertainment, art. etc. but those are not the only needs we have.

Virtual worlds and games are solution to that.

>The technology underpinning many jobs of the near future hasn't even been invented yet.

Sure, and there is nothing which can be invented that AI can't do.

You'll be a professional adventurer in a game, sponsored by companies
and followers or you might make weapons for those pro gamers. Or maybe
you'll be a tour guide in ancient Rome (or the 90's) or teach art
therapy or just gold farm for an mmo? What are your predictions?

That sounds so lovely but no. There is no reason why AI wouldn't be able to do that. But artists and artisans surely have things to do but it is unclear if almost anyone will pay for that anything. The thing is most people are not capable work in creative field. Also if most people can't create art for each others to sell then most will be unemployed. Unemployed people don't spend their meager money to something like art.

For jobs what we can find are something like politicians, countries' leadership, military leadership, corporate owners, some specific service work toward rich and prostitutes. Sure there probably are some rare jobs which we can't imagine now but probably 98% people are unemployed.

We don't even fully understand consciousness yet so saying that throwing
a bunch of things together in a neural network would work is dumb.

Well, we learned to use fire too without understanding how it worked. Also there are plenty of evidence in nature that when you throw enough of bunch of neurons together more conscious the lifeforms seems to be.

I don't believe too that AI is necessity at all but AI will speed things up.

Indeed and whole spectrum of STEM fields.

About Dr. Aubrey de Grey predictions and others who work in longevity field, do they also take into consideration how computers and AI will develop in future? What i have noticed in generally with people who work in different fields they don't usually consider how AI progress would affect their field. They usually think linearly.
