They probably hate the AI generated illustrations.

I asked the same thing about a different theuaob article that was recently posted, and it was indeed a reaction to the AI images. One person said they assume anyone who uses AI is an idiot, which doesn't seem to be the case here at all. I get it, but I also think we can have the nuance to move past that when interesting ideas are being shared. But I guess it's not impossible that down votes will get the author to change their ways, and then people will be open to listening?
