In that case, we can further automate this process and just leave humans out of it - pipe the student's generated essay back in, emit grade, done.

This reminds me of a moment that has stuck with me for a long time. Some time in the early 00s, I was wondering around town with a friend fairly late at night. We watched a waste truck picking up outside a building, there were stacks of Yellow Pages piled up, as they had just been delivered everywhere, like they used to.

My friend and I joked that they could have saved on transport and fuel by backing up the recycling trucks directly to the printing presses.

Reminds me of phone trees with a robotic voice telling to to press 1 for X, 2 for Y etc. When Google announced their automated phone tree handling, I thought, it's just two robots talking to each other over an imperfect medium, human language. Why not just connect the two systems together via API or something?
