I like what Rust offers over C++ in terms of safety and community culture, but I don't enjoy being a tool builder for ecosystem gaps, I rather spend the time directly using the tools that already exist, plus I have Java and .NET ecosystems for safety, as I am really on the automatic resource management side.

Zig, is really Modula-2 in C's cloathing, I don't like the kind of handmade culture that has around it, and its way of dealing with use after free I can also get in C and C++, for the last thirty years, it is a matter of actually learning the tooling.

Thus C++ it is, for anything that isn't can't be taken over by a compiled managed language.

I would like to use D more, but it seems to have lost its opportunity window, although NASA is now using it, so who knows.
