Not really. While there is a growing set of web-based application for Rust, it's not like PHP, where the very purpose of the language is the web. Rust is a system language before it is a web language.

WASM as a target is actually a great indication that it's a system language -- performance is a primary consideration.

You're missing the point. The point is that Rust came from Mozilla. Its mind-share started with web people and is expanding from there. What I'm trying to get across is that those social forces can matter more for adoption than just the tech's appropriateness, considered in a vacuum.

In that case, it came from Mozilla for working on a web browser, with primary goals of security, building sandboxes & language runtimes (js), and replacing an application-level cross-platform C++ core.

Which is very different than "web people", which in my mind implies webdev -- html/css/js + API server/db/caching backend.

Which also further explains why WASM is so far along (sandbox, security), much better than any association with webdev itself; but not kernel-level system development. (But if the web browser is an userspace OS... then it's probably not that far from it)

Off course it's a system language, there are even some that try to build an OS in Rust

Everyone is targeting WASM nowadays.
