We don't, we are happy with out distributed and networked computing. Most of us can't afford a mainframe, mainframe is owned by big corps, to play with one you have to go through a big corp. If you worked for a big corp, you still have to appease the priests or be one of them to play with one. It goes against the dream of "everyone should have a computer and be free to do with it as much as they wish". The biggest computing power that have been demonstrated in our history has been via distributed systems not mainframes.
