For me the best sci-fi universe to live in would be the one from Iain M Banks' Culture novels: Incredibly advanced technology means that lifespans are incredibly long and comfortable and economy/ currency is pretty much irrelevant at the personal level. There is no such thing as government, you can mod your body into absolutely anything you like and there is a proven afterlife at the end of it all. Furthermore, the whole society is maintained and kept stable by these benign Super-AI "Gods" called Minds, and there are a zillion wierd and wonderful places and things to see and do.

Yep, that'd do me...
