There is nothing in Rust that makes it inherently unfit for APIs or the web. To dismiss the entire language is simply lazy. Having GC also doesn't necessarily make one language superior to another.
While http ecosystem is still in active development, if there was really a choice between Rust and JS for e.g. writing an API I would go with Rust in a heartbeat.
Having a GC means having easier ergonomics to write data structures and distributed algorithms.
I do like a lot Rust's type system, just the ergonimcs aren't quite there yet.
You're correct, but "Rust isn't easy to use for purpose X just yet" is substantially different from "Rust is inherently unfit for X"
I do agree that there are holes, and that's part of being a young ecosystem, but I think you're being a bit too pessimistic. I understand this deeply, as I was once too! As things have evolved, my opinions have changed, though.
Please explain me where is this idea of slow development time coming from? Is it only because people try Rust for two weeks, cannot get the lifetimes and decide the development speed is slow?
