Exactly. I build automation tools for my company which have improved productivity quite a lot and put precisely zero people out of a job. Partly we find other things for them to spend time on, and partly it just turns out that we like to have humans doing jobs.

It is cliche at this point that HN is the place you go to hear software developers reduce all of the world's problems into simple algorithmic arguments which for some reason never actually solve anything. Not shocked that we are similarly incapable of understanding that algorithmically replacing a software developer isn't easy just because we think we know what the job is.
