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.
