Wow, lots of negativity here XD
I didn't expect that. I would probably not feel all that great if everyone disappeared, either, but I'd at least try to make a life of it.
As far as I know, power plants are autonomous. I'd just learn to fly my private jet from a book, as someone else said, and then go to Tokyo, which would probably still be in working, running condition. As long as the power plants held, I would be fine. And even if they didn't, I'd have access to all of the world's tools, so I could pretty much fix anything.
I think it would be cool to basically be the keeper of a desolate world. You'd have all of civilization's greatest accomplishments at your fingertips, and could do whatever. I'd drive a tank everywhere, wear tuxedos all the time for no reason, and generally be the random person I've always been.
