I think they're all natural niches, because Rust's performance and ability to tightly control memory allocation are over-promoted and the strength of the type system as a means of ensuring correctness at compile time is underpromoted.

Especially web use is one of the biggest places you want to be able to rely on the compiler, aided by patterns like the newtype pattern and the typestate patterns, to catch as many potential DoS or security bugs as possible.

I use Rust as "Haskell, but without having to put up with writing Haskell". (Or, more commonly, I say that Rust is the sweet spot where you've taken pretty much everything functional programming has to offer before you start falling off a return-on-investment cliff.)
