I think it will be what it has always been. We will get more efficient/productive, maybe even exponentially so, and that will mean there will be a lot more wealth. Everyone will be better off than they are now but everyone will keep complaining they don't have enough. Someone 100 years ago looking at the world today would think there is so much wealth and abundance that everyone must be happy. Someone lower middle class today had more comfort, art, access to knowledge, access to entertainment, etc. than the king of England did 500 years ago.
