It's funny. I hear two different things, all the time. "Rust is easy to learn" and "Rust has a steep learning curve". Personally, I found it to be the latter, and that's as a serial dabbler/language polyglot. I had a bear of a time wrapping my head around lifetime annotations, and needed someone already familiar with them to sherpa me through that stage.

I think it does a disservice to say, "Rust is easy to learn modulo these two really challenging concepts, plus some other things you are likely unfamiliar with". Python is easy to learn. C++ is hard to learn. I'd rate rust as medium difficulty.

It sure is enjoyable though, I don't think that's ever in doubt.
