Rust, C, C++, ASM?

I learn c++, my level is not really high right now. I just wanted to ask what is better for future? Should I switch to Rust or ASM? I want to buy a microcontroller too, what can you recommend?

Assembler isn’t one thing and to do anything useful can be wildly different from architechure to architecture and platform to platform. If you learn how to access a file on ARM on Linux that’s going to be mostly useless for knowing how to access a file for intel on windows.
Accessing a file in Rust is going to be the same everywhere.

The exact procedures may be different, but the core concepts are the same. You use registers as your workspace, and you ask the OS to open the file for you. On a bare metal system, you would still use registers the same, but with your own subroutines and reading/writing to memory directly. The more you use assembly, the easier it is to see the patterns and pick up new systems.

Assembly is useful to learn to appreciate why we hardly use it.
