It is difficult so say when an AI will be capable of outdoing most programmers. It will eventually get there but it is a difficult challenge.
A world with no need to work for a living would be a paradise. It would require that everyone be entitled to the value created by AI's and not just a small group of trillionaires. Some people say that having to go to work is the only thing between most people and total deterioration. I don't believe most people would go and drink themselves to death out a lack of purpose in life. Did the leisure classes of yesteryear do that? No, they didn't. Many of the pioneers of science and philosophy of past centuries were men of means.
I think work is something that everyone should do. Having said that, what most are doing now I wouldn't classify as work as it is mostly slavery to create the irrelevant.
That is another way of saying roughly what I was getting at. Everyone should have the opportunity to find something meaningful to make an effort for. I'm not so pessimistic as to think that once freed from the rat race most people wouldn't be able to figure that out. It could be something as simple as helping the old lady next door or anything we currently do not have a market for.
