people that are in charge of them are usually the dumbest people ever.

I think that’s actively encouraged by management in some areas: put the dumbest people in charge to make the most irritating frustrating system possible. It’s a feature of the system.

Some of the most irritating systems I have interacted with (government disability benefits administration) actually require “press 1 for X, press 2 for y” and if you have your phone on speaker, the system won’t recognize the touch tones, you have to do them without speakerphone.
