Maybe you are tech nerd so all the probable tech progress would amaze you. But unless you yourself would literally do time travel (and be treated like a primitive Neanderthal), your level of satisfaction would most probably be the same since all amazing and cool becomes a new baseline rather quickly, and curiosity and longing for next future would be there again.
We could also end up in millenia-spanning dictatorship of immortal piece of scheize egomaniacs like stalin, hitler, puttin', trump and so on and on. All of them would kill millions to achieve that, in a heartbeat with no remorse.
We could also destroy our ecosystem beyond easy repair and live in postapocalyptic mad-maxesque world (sure it will bounce back in a million years or two, but we would most probably be wiped out along the path). I look out of window on a dense beautiful wild forest in full bloom, doesn't get much better than that.
Nah, these are pretty good times we, most of us at least, have right now. If you are not happy now, chances of being happy some other time are slim.
