Nerds became an industry field - that's what it happened. Back in the 90'ies we were doing IT things because it geniunely interested us, not that it would "net us high salaries". I'd do this even if you didn't pay a single centa because it triggered my dopamine receptors.

Then the world digitalized, and people who do not have any interest in computing and computers in general became "experts". That's when the ball begin to roll. This created people who can't give a french fry about the work they are doing? Quality? Efficiency? What do they matter, it was a job you did for 9-5 and you got your salary. If money was in say, haystacking, they'd be doing haystacking.

Now whenever someone utters "crypto" I do a doubleback and realize they mean cryptocurrencies, not cryptography. I do not expect any of my new hires to know the word "grok" (other than the AI of course), enjoy science fiction or any nerdy things we did. IT was a community where like minded people were working, now it is not.
