Depends on the point of view regarding using languages with automatic resource management.

I learn all languages that I find interesting, even if I don't use them, because I am a systems programming nerd, in languages, graphics and operating systems.

So it is always interesting to have an understanding of what Rust is all about, even if I will never work professionaly with it.

Imagine trying to make some sort of MP3 player using an MCU. You’d be able to use MicroPython for the controls, but for decoding you won’t be able to get away with it, and you’ll need something like C/C++/Rust.

You are downvoted, but for some things, no there isn't. MicroPython can be very useful for some use cases and it's safer than C.
