I think it goes back to the huge amount of anti-AI sentiment that's out there today. Any AI accomplishment gets undersold by haters, i.e. people maintaining that the Navier-Stokes solution was stolen, people saying that Lean proofs can't be relied on, exploits like PHP2Shell are esoteric and not usable in the real-world, etc. Those are just comments I recall reading off the top of my head but I could find sources if anyone wants. I think it's just a way for people to cope and fool themselves into thinking that this whole AI thing isn't a big deal and will just blow over.
