How does anyone get there? There's too much about too many things to learn to think one knows it all! Besides which, even in specialist areas, new stuff is being learnt & found every day that changes our knowledge.I don't care how highly people think of themselves. What I have trouble with is arrogance (to lay claim to that one is not capable of) If someone can do something well then I'm fine with a bit of self publicity. I seem to have met an awful lot of people through my current living circumstances who have trouble lacing their boots up without tying both together, but advertise themselves as a lot of things they aren't.
This sort of arrogance does over time lead to stupidity. If one believes, as in this mans case, that he is of a level of intelligence that he no longer needs to learn then he and anyone like him, stop learning. We used to get a lot of high level academics visit here. It was interesting to watch those who were fundamentally intelligent go about a task and those who it seems had specialized themselves into stupidity on every other endeavored not pertinent to their specialist subject.
There is a phrase that one can't prise out of this person with a crowbar and that is 'I don't know.'
