I find that I don't want to use any other programming language now that I'm becoming proficient in Rust. Is this common?

I'm starting to feel like Rust is the exact language that I want for all of my projects. It feels like it has the best of both worlds: high level features, and native performance. It feels like it's what programming languages should be. Sure, there is room for improvement, but I just don't see myself wanting to return to C++, C#, or Python. I'm starting to forget how to use those three languages, and I feel like that would be a lot of knowledge to lose, although I guess I don't really need those languages anymore.
