I'm not sure that there is a recession of corporate support from C++. Just that the proportion of companies that need C++ is smaller than it once was.

I like the safety promise of Rust. But the complicated interop story with C and C++ hurt it a lot. I mean, in a typical codebase, what proportion of bugs will be memory-safety related vs other reasons? Ideally, we could just wrap the safety-critical bits in a memory-safe wrapper and continue to use C and C++ for everything else.
