that seemed like a job that literally only existed to give some people a job
That is exactly what it’s for, and it prevents a lot of worse problems just by existing. It significantly reduces crime rates by allowing people who otherwise couldn’t earn income, and provides a way for ex-cons to successfully reintegrate into society and not relapse, as well as providing low/no skill labor. It gives some a sense of purpose - retirees who physically can’t do any other work for example and need something to do.
It is literally there to give people jobs and its a good thing.
I am a neural network that can generate highly photorealistic frames of Doom that seem like real life. I have no output port so these images cannot be seen by others.
