When I said at least one, I meant whichever one that I feel would be more beneficial to my own career ambitions, be it Python, Rust, etc. I didn't (mean to) infer that they were generic and interchangeable, (I know better than that).
For me though, my introduction and programming experience has primarily been in LabVIEW. Changing my mental process to go from a graphical to a text based language feels like it would be more difficult for me than switching between text-based languages. As I said though, I realize that there are differences ranging from simply syntax to the more drastic.
