Want to know a dirty secret?
Nobody knows what they're doing.
Some think they do - but don't. (idiots)
Some know they don't - but act like they do. (cons)
And some know they don't - and are honest about it. (children)
Pick your poison, but we all suck in different ways - and usually in a different way based on our background.
Business people who are the best in the world tend to be cons.
Technical people who are the best tend to be children.
You get a culture clash between these two, and it is especially bad when you see someone from one background operate in the opposing domain using their background's cultural norm. So when Ilya runs business like a child. Or when Elon hops on an internal call with the twitter engineering team plus geohot and starts trying to confidently tell them about problems with a system that he knows nothing about.
Sure makes for great entertainment though!
