"Maybe you shouldn't worry about how long your son's job will last? Maybe he enjoys what he does?"
Yes that he does but losing ones first job is not good for a young person's psyche. This is a young firm which prides itself on its math modelling and algorithms. But I recall the disaster of Long Term Capital run by Nobel prize winners using the famous Black-Scholes equations. So I'm not very comfortable esp when he doesn't really need this stupid job. I guess young folks are thrill seekers. At least he doesn't do drugs or alcohol nor drive recklessly.
