It is depressing that I had this same argument in college a decade ago and people are still so cavalier about not optimizing their code.
Companies will invest in what pays the bills. And hyper optimising for customers with no money isn’t it.
Nobody has any actual clue what they're doing, everyone keeps writing code for the compiler hoping for the best and the rest of the world has to buy new machines because the programmers of the last decades sucked.
That, btw, includes most of you people reading this. You're fucking welcome.
