It's not exactly a misconception, when companies are pitching AI as a full and complete replacement for human employees. People are just reading the billboards on the side of the road.
I always found advertisements for AI to be so strange, why would you advertise your AI to the public as a danger for humanity that will also put everyone out of work? Such advertising would only appeal to sociopaths, but of course that's because it's intended to appeal to CEOs.
It is just some chuunibyou bullshit to say "Look at how powerful my LLM is!". It is a dumbass publicity stunt, you're just reading into your preconceptions hard.
