"I believe the best software is written by small groups of people who have both passion and vision. Passion is easy to define; you care so deeply about something that it wounds you if it's done poorly. Vision can mean different things, but I mean the ability to not just come up with new ideas, but to actually be able to see how they would integrate with people's lives. Vision without passion gives you a guy who sitting on couch saying, 'Flying cars! Wave of the future! Mark my word, the guy who invents that's going to be rich... pass the chips.' Passion without vision gives you America's current political situation, where we allow huge companies to destroy the world but pass laws to make sure nobody marries a turtle."
