Since I learned programming at school, I did not really have a choice. I had to learn Delphi (Object-Pascal), JavaScript and PHP. I actually wanted to learn C++ and ASM, though.
If I had to choose a language today, I'd go for Rust (GameDev, backend, mobile, etc.), JavaScript and TypeScript (frontend, backend, PoCs and tools), and maybe ASM basics, since ASM is useful knowledge, even when you don't write actual programs in it - in order to understand how a program works on the lowest software level.
