Whether this means that you are wrong about when prosopagnosia is a continuum, or whether it means we should characterize how things work for me in terms separate from prosopagnosia (and thus perhaps in terms separate from face-blindness), I do not think it is productive for you to basically insult me and everyone like me by attributing our behavior to not trying hard enough. I've tried quite hard.

It's very socially bad not to be able to recognize people. I pay high costs for this inability and I would love to eliminate it if I could. I think (as the OP suggests) being aphantasiac might make it difficult for me to remedy this inability, because having a visual memory might be the best (the only?) way to record features of faces well enough to recognize people you know mildly well. I am aphantasiac and that too is something I cannot remedy. I would appreciate not being lumped in with assholes.

You think we will make progress by learning to use AI in certain ways, and that assignments can be crafted to inculcate this. But a moment's acquaintance with people who use AI will show you that there is a huge divide between some uses of AI and others, and that some people use AI in ways which is not creative and so on. Ideally this would prompt you to reflect on what characteristics of people incline them towards using AI in certain ways, and what we can do to promote the characteristics that incline people to use AI in productive and interesting ways, etc. The end result of such an inquiry will be something like what the author of this piece has arrived at, unfortunately. Any assignment you think is immune to lazy AI use is probably not. The only real solution is the adversarial approach the author adopts.
