.... why not? Rust was designed as a systems language but it pretty explicitly targets things which are outside that sphere as well.
(unless you're joking here; hard to tell)
Rust's clunky syntax and lack of higher order abstractions can makes some programming pretty frustrating. Working on a compiler using it atm... missing recursion schemes and GADTs for example 😭, also lots of explicit boxing of pointers.
I'm much happier using it than, say, Ruby, Python, or JS, and I'm making the tradeoff to use it because I want easy access to the Rust ecosystem, but it's interesting to see some of the friction points.
