I am surprised that most data entry and billing jobs haven’t been automated already. After a quick Google check, it still seems to be a hot topic for human workers.

I do agree with you though. Unless we are talking about multiple choice tests, grading should be a human teaching a human to be human. The few teachers I had that truly gave a shit about me as a person remain my personal heros over 30 years later. (I was a problematic child, to say the least. I didn’t find out that I was ADHD until my thirties and I think there might be some autism sprinkled in for flavor. Neither of those were actually recognized as issues when I was a kid.)
