I like Rust, have dabled a couple of times in it, see a possible great future for it in the next couple of decades, given that it is being adopted by the likes of Google, Microsoft, Oracle among others.

However I will keep writing C++ to go along my Java, .NET, nodejs production code, for the time being.

Rust is still lacking in IDE support, mixed language debugging, OS SDKs I generally use, integration with binary libraries, not everyone on the teams is willing to add yet another language to the mix, NVIDIA GPUs are designed for C++, and newer features make it easier to write safer code, in spite of its C underpinnings.
