Seeing people pondering what time they'd want to travel back in time to... What springs to my mind is: Could I nudge the computing industry towards a better present with the gift of foreknowledge?
To an extent I don't think I would be able to nudge things too much, since my read of computing history is that we needed to go down the path we did simply to have the tools we needed to build our present.
