What fascinates me most here is when and how he and Page transformed over into doing public business with their research, not just keep working on it academically. Lots of my friends are working through their often very interesting thesis projects, tangled up in this academia lifestyle, but they all seem to be drifting away further and further from the ability to ever put this into a business context. Not that this is necessary or what many want to do with their research, but I really was just curious how Sergey and Larry made that shift.
