Programming

That's very closely related to something I've come to think about tech: nerd equivalency. If there is a computer involved, then a nerd is required and they are all interchangeable.

Basically, someone says "we're not moving fast enough, hire another nerd!" and nobody in the chain of command or in the hiring process has a clue which particular skills are required, assuming that everyone can do everything.

That's why so many corporate projects have what amounts to random people doing randomly assigned work producing insecure, unreliable products with obscure and even hostile UIs.
