I'm not sure if many realize, but in such a world very few would actually work. All the rest will play.
Right now, the reason some people bust their ass working, is being they can get paid more and live a higher quality of life. If everybody get everything they want, why would anyone work?
But remember, AI may change things a lot. It'll not be a problem of you will work so I can sit, but more a problem of you and I will have some machines working for us, so what's left for us to do..
One of the implications I was talking about, is that the human psyche is built to function under survival pressure, when the pressure is removed, then depression may occur. So it's going to be very tricky, unless we train ourselves to function in a different mode.. where we are the masters.
