I don't agree that Rust tools are more sophisticated and they definitely are not more abundant. You just have a language that is more anal up front. C++ has many different compilers, analyzers, debuggers, linting tools, leak detectors, profilers, etc. It turns out that 40 years of use leads to significant development that is hard to rebuild from scratch.

I seem to have struck a nerve with my post, which got 4 downvotes so far. Just for saying Rust is not actually better than C++ in this one regard lol.
