There's always someone willing to write COBOL for the right premium.
I'm working on Rust projects, so I may have incomplete picture, but I'm from what I see when devs have a choice, they prefer working with Rust over C++ (if not due to the language, at least due to the build tooling).
Writing C++ is easier than writing Rust. But writing safe multithreaded code in C++?
I don't want to write multithreaded C++ at all unless I explicitly want a new hole in my foot. Rust I barely have any experience with, but it might be less frustrating than that.
Anecdotally, my "wow, this Rust business might really go somewhere" moment was when I tried adding multithreading to a random tool I made (dispatching tasks to new threads).
Multithreading had not been planned or architected for, it took 30 min, included the compiler informing me I couldn't share a hashmap with those threads unsynchronised, and informing me on how to fix it.
I've had similar experience when the compiler immediately found unsynchronized state deep inside a 3rd party library I've been using. It was a 5-minute fix for what otherwise could have been mysterious unreproducible data corruption.
These days even mobile phones have multicore CPUs, so it's getting hard to find excuses for single-threaded programs.
