C++ has evolved immensely in that same time. I still would NEVER use C++ for anything new, now that Rust exists.

Why should I use Fortran, for anything that isn't maintaining legacy code?

Rust might exist, but it isn't shipping in console devkits, or industry reference game engines, just to quote two examples where it has yet to achieve parity with C++.

Fortran is nowadays a DSL for computational codes. If you don't know why you would or could use it, you're not the target audience for it.

Calling it a DSL is a bit rich given the history of computing but at least that way at least CS and developer types will know how to regard it.

I like modern C++ much better than Rust. I am 3 times more productive in it and don't have to fight the compiler for hours. And RAII is a simple idiom that prevents 95% of actual problems.
