I think the idea that AI leads to some kind of universal basic income or frees us up for leisure is misguided.
There was a point in time when the majority of people were basically required to work on producing bare necessities like food. But we have already come far past that, where we could easily produce more than enough food for everyone on earth with a relatively small amount of workers.
There is some work that is still more or less essential to a healthy society that humans must perform, but many many people are doing something non-essential (and those doing essential work are often not rewarded proportionally to the "essentialness" of that work). We invent different kinds of "work" to fit into the capitalist machine that we have built, not because it is required for human sustainability or enriching our lives in any way. Some work might be actively harmful to society in every way other than keeping capital flowing around in some circle, and more and more of that capital is being captured/hoarded by some ultra wealthy individuals or corporations and not recirculating at all.
The problem is allocation. We allocate everything via capital, which I recognize has had some very positive outcomes at certain points in history, but may be reaching a point of making less and less sense for the modern world. The work I do honestly does not contribute much of anything to anyone. I do it because I am paid to, and I use that money to pay for my families needs. If my job was automated I would not be freed up for leisure, I would need to find some other work or service to be paid for to survive, regardless of how "important" that work is.
AI eliminating a swath of non-essential work does nothing to help with that allocation issue, in fact it probably ends in a worse overall allocation. AI may legitimately assist with some slice of "essential".work, but probably not that much of it.
