For me it all made sense when I heard that IQ/g-factor basically vanishes in the absence of time pressure (heard if from Richard Haier on Lex).

For a very narrow range of professions, like ATCs, time is absolutely critical but for most it does not really matter that much. Especially in many STEM fields. I think people in a broad IQ range can build abstractions and acquire intuitions about pretty complex matter. From this view-point ability to concentrate for long times, curiosity etc. seem more important than "raw-compute".

"if you value intelligence above all other human qualities, you’re gonna have a bad time" - Ilya

Timeless statement imo, even in the absence of AI
