>Stephen Wolfram does add a few self-congratulatory remarks.

This is the man to a T. I think he would have done well in Victorian England. He is a clinical narcissist, and is incapable of mentioning any topic, subject, or fact without inserting a remark about his achievements.

It gets comical once you get to know him. I'd start pointing things out to him if I ever spoke to him.

"Stephen, this steak is delicious. Didn't you invent the software that allowed the design of the temperature sensors on modern grills?"
