I kinda don't really like C/C++ anymore. I use it because it's typically the only (or best) choice for low-level stuff or integrating SDKs.
Rust looks pretty nice, actually, just read some tutorials. Still will take a while for everything to be updated. Also Google is pushing Carbon as a C++ replacement.
And C# is nice as a language, I just don't like the disconnect between using managed and unmanaged code. But I think it's fair to say C/C++ is on the way out.
