If you ask HN, HN will almost always tell you to learn Rust.
But HN is its own echo chamber. Rust is practically unheard of outside the enclave. If you learn Rust, you will be obliged, in short order, to learn other languages that are actually useful in your target area.
So, find out what languages are used there, and learn those. The only bad mistake would be to start with C.
That said, it is not a mistake to learn Rust. Just don't expect it to be usable at work.
