1. Hype over Rust. 2. Pragmatism because of the many complexities with imperative programming and multi-tasking in a more and more multi-core world. 3. Hype over Rust.

:-)

I personally find Rust so ugly that I refuse to learn it. I don't understand why things like "let mut" are even allowed to exist. Why not simply "create" or "var" for "let mut" and "define" or "def" for "let"?

I am not trying to start a flame war, rather I believe I'm documenting my own ignorance of Rust, the language which I believe you are subtly referring to. I tend to learn languages from an aesthetic angle: If they look beautiful and practical to me (like Python with type annotations), I learn them. Otherwise I steer clear of them while waiting for the world to become ecstatic over them and cool down again a few decades later.
