My sympathies.
Read somewhere that the practice of defending one's thesis was established because buying a thesis was such an established practice. Scaling that up for every single text is of course utterly impractical.
I had a recent conversation with someone who was convinced that machines learn when they regurgitate text, because "that is what humans do". My counterargument was that if regurgitation is learning then every student who crammed, regurgitated and forgot, must have learnt much more than anyone thought. I didn't get any reply, so I must assume that by reading my reply and creating a version of it in their head they immediately understood the errors of their ways.
That's true, and that's one way to approach the topic.
I generally focus on humans being more complex than the caricature we need to be reduced to in order for the argument to appear plausible. Having some humanities training comes in handy because the prompt fans very rarely do.
