@LefterisJP: How will AI's radical abundance benefit everyone vs just big corps?

Whenever I talk to an AI accelerationist or listen to a podcast about how AI will automate all our jobs in the next 10 years (from example from @tamaybes at the Hard fork podcast) there is always this notion of radical abundance and that we would all be sharing in it. That somehow we would all find meaning beyond work and also have much richer lives and access to many more things than today. That all sounds really great but also I don't know how it would work out. AI is being built under a system where big corporations build it and capture the rewards. How are we going to go to a system that will benefit everyone and humanity as a whole and not one where this radical abundance is going to be captured by a few and the rest of us are going to be slaves to them and their AI? Because under the current system I see the dystopian scenario as the one that would naturally come if things progress as expected with this technology. The Utopian radical abundance scenario where everyone benefits seems to me like it's missing some key pieces of how it will be implemented. I am really curious what are people's thoughts on this as AI replacing lots of jobs seems indeed more and more likely.
