I hope your son can succede at work. I think he will need to make small talk and have regular conversations with people before he can advance socially that much. That was so with me. I could write an above average essay and I could solve fairly complicated math problems, well enough. I wasn't able to make small talk. Lacking this basic skill, nearly got me killed. It is more important than people think. I mean, being quiet and obedient works when eveything else works also. When the outisde world falls apart and the inside world falls apart also, being quiet and obedient can be very hazerdous and make oneself a target to predators. Emotionally vulnerable and naive people are valuable to criminals, I do know this from experience. I am lucky to be alive.
