John Carmack's QuakeCon 2013 Keynote

Don't you just love John Carmack? He's a skinny little towering titan millionaire super genius, and a nice guy to boot. His latest keynote at QuakeCon before running off to join the team at Oculus as CTO is, as always, fascinating and dense. He participates in technology at a level of detail that would kill most people, and he loves to talk about his observations, conclusions and predictions.

Check out the below video – and join the crowd in egging him on whenever he tries to chastise himself for spending too long on each topic. Be warned: make sure you're seated comfortably, it's a good two hours and forty-seven minutes long.
