The current constraint is "you need to produce to have things".
If one company's AI takes all the jobs, and thus does all the producing-to-have-things, the constraint transforms into "you need that company's permission to have things".
Hence the top-level question.
And under the capitalist system, if nothing changes, the "new" distribution system is indeed not going to favour them - at best there would be some sort of UBI, and at worst you would be left to starve in the streets.
However, i cannot see how one can transition to a new system, and yet have the existing powers in the current system agree and not be disadvantaged.
Say ~5 million jobs in the next 10 years are automated away, which industries do those people move to?
With college being exorbitantly expensive, that locks out many people from re-skilling in other fields.
As people race to other industries, that forces down wages because now there is a larger pool to select from.
How do we ensure people are taken care of when UBI is all but fiscally impossible in the US?
At the risk of sounding like a longtermist, I think that when all is done, the result will be a net positive one, but it WILL cause strife for many people - probably me included. But I refuse to keep my childern's future hostage because I might have to reskill.
