The utility I get from Joe Rogan interviewing experts is that he asks a lot of clarifying questions to help bring the material back down to a more understandable level. I love Carmack's talks because I am in the same field and can usually follow him, but I cannot imagine a layman being able to keep up.

Why do you want a layman to keep up with him? What an utter waste. He knows his audience and that's great.

Relax... he can do both, talk to laymen and his specialized audience.

No, what makes Carmack interesting is his discussions about highly technical topics at a moderately advanced level. There are plenty of people who are more than happy to explain what functional programming is at a basic level for laypersons. Carmack is not that.

I assume you're American because of your need to dumb everything down instead of respecting intellectualism as is.
