Rust is being used where it makes sense--generally security. So, gamedev won't use it for main loops but will use it for networking code. The crypto Ponzi brigade chose Rust for a reason. Some of us who write communication stacks (TCP/IP, CANBUS, etc.) try to use Rust whenever possible.
However, you are correct in that Rust popularity is growing, but it's going to be slow. If you look at the TIOBE index, there is a limit as to what Rust can really displace. A lot of the top languages are now GC-based, you're not going to reach for Rust if you can use those. So, Rust can realistically only displace C, C++, and ... nothing else. That means almost 75% of programming language use cases aren't even in scope. And C programmers really aren't going to gravitate to Rust as it's more of a C++ replacement.
So, you need a specific usecase (security) or a greenfield project that would use C++. That's going to be a slow climb.
