John Carmack was also constantly working on the cutting edge. I think that makes a big difference. IIRC from reading MoD, he was the first person to get true side-scrolling working on an x86 chip, before it was thought to not be powerful enough vs the chips used in consoles at the time. Problem is that most of us just don't get to work on the cutting edge usually. A lot of the software that needs building often doesn't need much in the way of creativity.

Is John Carmack also a genius? Sometimes I can’t tell, but I suspect so.

If you’re going by IQ I’d bet he’s at least in the 145-159 highly gifted range.

I'd comfortably add 30 points to that, at least.
