I don't think it is fair to claim computers are about putting people out of jobs.
Computer used to mean "human who does math". Before machine computers, we had human computers. Machine computers replaced all of these human computers.
- Video games
- Medical device firmware
- Synthesizers
- Detailed universe-scale physics simulations
- Mars rover control software
- The Linux kernel
- Medical device firmware - hardware control layer for medical devices, which are used to aid in medical procedures.
- Synthesizers - help to make music.
- Detailed universe-scale physics simulations - help to make certain physics problems more tractable.
- Mars rover control software - helps to remote control rovers.
- The Linux kernel - control layer that sits between firmware and actual applications, pretty much just a common shared library so apps don't have to each ship with a full stack.
I don't really see your point here. None of these examples counter the argument that software is created to automate human labour as much as is practical.
Video games are an interesting category since they're entirely enabled by software: I can't imagine anyone driving a video game manually (note I don't consider things like Chess, etc software to be video games in this context; more things like FPS, racing, etc). I do remember as a kid I thought that there were actually little people doing the stuff in video games though.
All of these things existed in pre computer form.
A scheduler used to be a person putting punch cards into a machine.
