I have written in dozens of computer languages, including specialized ones that were internal to Pixar (including one I designed). I spent decades writing C and C++. I wrote bit-slice microcode, coded for SIMD before many folks outside of Pixar had it.
I wrote the first malloc debugger that would stop your debugger at the source code line that was the problem. Unix workstation manufacturers had to do an unexpected release when this revealed all of the problems in their C libraries.
I am a better programmer in Rust for anything low-level or high-performance. It just keeps me from making an entire class of mistakes that were too easy to make in any language without garbage-collection.
Over the long term, anything that improves quality is going to win. There is a lot of belly-aching by folks who are too in love with what they've been using for decades, but it is mostly substance-free. Like people realizing that code marked "unsafe" is, surprise, unsafe. And that unsafe can be abused.
