C/C++ oldtimer myself, yep Rust is basically C++ template metaprogramming. So Rust does this thing way better, but as you says it does other things less good. Exactly like Java with the facility to run on different platforms (well, sort of) for example.

C/C++ is hard because it's the ultimate multi tool!

I use Python BTW when I don't need the fancy stuff, maybe the death of C/C++ will be that of a thousand cuts, one specialised language for each specific C/C++ use ...
