I like to think he'll always sort of believe this. At heart, in his shiny metal heart, he's a futurist, and there's this technological optimism in that which nothing can shatter, because you can't stop believing in things that haven't even been invented yet. If the best thing you can build is yet to be built, then you can keep believing that it's perfect.

Oh, man, that gives me Ideas.
