Maybe there's some truth to what you're saying. But at the same time, there aren't many alternatives that tick all the boxes C++ does (performance, portability, maturity and stability). Together with the amount of C++ code that exists, I don't see C++ going away anytime soon.
Ironically, if one wants all of those things, the best alternative at the moment may be the C language.
