At that point, if AI can do 75-99% of what you do... Why should anyone pay you to live/survive?

Humanity is having those discussions, heck you are in one RIGHT NOW not some Hollywood future.

What is coming of those discussions is the ownership class balks at the idea of raising their taxes (see recent interview with bezos), and therefore balks at the idea that you or I should have any value beyond what we produce... And if AI can replace you or I, well how do we survive if we can't produce in a technological society?

I think you are blinded by an unprecedented optimism the rest of us simply cannot afford to entertain.

Go ahead and have that conversation with the billionaires running a worldwide satellite grid of data centers to power their AI surveillance dragnet and autonomous robot soldiers. See how far it’ll get you.
