I believe it's inevitable. But I would have given a very different answer even a few years ago. What strikes me the most though is that C++ is that it's not being succeeded by a new better C++ but instead it's being slowly replaced by multiple languages at once. C#, Java, Go, Rust, Swift, and JavaScript, (and maybe even python) are all replacing C++.

In 22 if someone wants to make a general desktop app they'll probably use web technologies, or python, or java. If you do server development it's Python, C#, Java, Ruby, or Go. Embedded development is predominantly pure C. C++ is used but less often. Gaming is still a singular C++ affair but I'm starting to see C# make headway and now Rust is gaining traction. I've seen more game developers excited about Rust than I have about anything in the last 5 years.

You can see it happening slowly, as more and more technologies are coming out and chipping away at it's use cases. Unless you're targeting game consoles, or a very specific rare domain, using C++ might be more of a handicap with so much better options out there.
