That CNBC article seems to be supporting my position, not yours. It's quite clear that autopilot is an aid, not an autonomous pilot substitute, and that the pilot still handles certain parts of the flight and must be ready to take over if something happens. Unless your point is that everyone thinks autopilot means more, and this article is correcting that notion?
I fully agree that if just about everyone thinks a word means something, then it means something. I'm not trying to argue based on some technicality. What I am arguing is:
1. I'm not at all sure that this understanding of "autopilot" is as ubiquitous as you say it is.
2. Even if that understanding is nearly ubiquitous, I can hardly fault someone for using "autopilot" to mean something simpler if they are doing so because they are familiar with actual autopilot systems and are naming by analogy to the systems, not to popular understanding of the term.
3. If people really do all think that "autopilot" means a fully autonomous system, the fact that no such thing is found on real airplanes means that they're a bunch of idiots, and I'd really like to know where that idea came from.
