The fact that this could happen is widely known and has been talked about for years now. What to do about it is the real issue. I've seen David Shapiro and many others tangentially talk about UBI and similar "post AI economics". The dream was that the machines could do the housework whilst we all painted, wrote music and built beautiful wood furniture in our sheds. It still could be that way, but we need to sort out responsible sharing of resources first, and humanity has never been able to do that. We actively try to earn as much as we can, for the very reason of getting access to the resources that others don't. So often now, it only results in standing still or sliding backwards. I feel like 20 or 30 years ago, the average person seemed to have more disposable income.
