Learning Rust can be challenging, especially if you're accustomed to Python or Kotlin. The Rust compiler is strict, which can be demanding for programmers. However, the effort can be rewarding due to Rust's advantages. Expect a slower pace of progress, as tasks that are straightforward in Python or Kotlin may require more time in Rust. The difficulty level is higher, but with motivation, it's certainly achievable.

In my experience, the more programming languages and frameworks you know, the easier it is to learn a new one. So it depends on how much you know already and how much you want to learn.
