Like I'm sure the grad students working for Euler learned a ton generating logarithmic tables by hand, but it proved to be useless in the end. Could having a solid grasp on memory management/access in C be the same?
I think this is why obsolescence can be hard to predict.
Like if in 30 years all code is run and managed by ai bots, then all this debate about "it's important to know how to code!" will seem really silly.
