This sounds like Robin Hanson's idea of the future. Eliezer would probably agree that in theory this would happen, except that he expects one superintelligent AI to take over everything and impose its values on the entire future of everything. If Eliezer's future is definitely going to happen, then even if there is no truly ideal set of values, we would still have to make sure that the values that are going to be imposed on everything are at least somewhat acceptable.
