"For people who make inventions, whether they make scientific inventions or artistic inventions, they're driven by pretty much the same thing. It's some mistrust from somebody saying it couldn't be a certain way, and overthrowing that. But that can happen at any point in history, at any time you come along. It doesn't get better or worse because you're born in this era or that era - I think it's more individualistic. It comes from within, you know, it's an internal thing."
