I think Chris Anderson is totally wrong here. I am currently the smartest person in the room. I don't CARE if I'm also the dumbest person in the room. He's still wrong. ;)
(while talking to another senior person at Microsoft)
ChrisAn: "Have you driven a feature from scratch?"
Other: "Uhm, yes. I've worked on various platforms for the past 30 years, worked on the first release of DOS for Arabic and Windows for the Middle East".
ChrisAn: "I'll take that as a yes"
Remember to self, you are never the smartest person in the room... ever.
