Highly recommend the 2021 documentary "The Automat" if you're into this.

I was just about to post the same thing. It's a very enjoyable watch. Quite light and digestible (~80 min runtime) and featuring Mel Brooks and Ruth Bader Ginsburg.

Currently streaming for free on Kanopy, which is often available through local public libraries.
