I remember one town hall where he was asked "If you had to start over again, what sort of company would you start?" and his answer was "I wouldn't, all the good ideas are already taken."
It's a thing that has been said by various people throughout history and it has always been a ludicrous assertion before. Why does he think it's different now?
If what he meant was "I'm out of good ideas", that's different, of course.
