It's more of a cultural thing of something getting extremely popular too quick.
When something rises to an absurd amount of popularity really quickly it becomes stupid. People like to talk shit about it. It happens with bands and crocs.
People have forgotten just how revolutionary the LLM. The hype is justified.
I'm telling you if somebody next week invents cheap space cars with lightspeed drives that cost only 4$... within a year those space cars will be referred to as junk and overhyped by the very people who use it everyday.
That's how humans are.
