The big ego stuff and always needing to feed it with claiming credit for everything reminds me a lot of narcissistic personality disorder, which is caused by childhood emotional abuse, so I think we should just humor his ego and recognize it for what it is, that is be kind and understand what causes that sort of thing, while not letting it distract us from the value of the research he’s doing. Intellectually Wolfram is clearly a very intelligent person; emotionally he is underdeveloped.

I doubt that any personality disorder has as its sole cause "childhood emotional abuse", so I would not want to indirectly someone's parents because of their perceived personality flaws.

Good point. I encourage you to read up on the personality disorders, they are fascinating.
