C++ can stay, but people can make a decision not to use it for anything and not to take any jobs involving C++ (or other systems/bare-metal-ish languages).
I've written a fair amount of C++ in my day, and this seems totally unacceptable to me.
Also my opinion seems unpopular on this topic, so I suspect some group of people that really want to get behind C++ don't like that kind of talk.
Whatever though. Rust and other newer languages are kind of giving the spaces C++ works well in a run for its money and in other ways just completely blowing it out of the water in my opinion.
