Yeah that's definitely optimistic. More like 1-6 months depending on how intensively you learn. It's still worth it though. It easily takes as long to learn C++ and nobody talks about how that is too much.

Yes. I learned Rust in a weekend. Basic Rust isn't that complicated, especially when you listen to the compiler's error messages (which are 42x as helpful compared with C++ compiler errors).

Damn. You are a smart person. It’s taken me months and I’m still not confident. But I was coming from interpreted languages (+ small experience with c).
