Rust works well for toolchains where speed counts and you can control deps, but it's a much bigger ask for server-side app logic where teams lean on JS and its libraries. Switching an established stack to Rust hits hiring and maintenance friction fast, especially with async and lifetime bugs. For Vite's community, requiring plugin authors to redo everything in Rust would probably destroy most of the value users care about.

Well that's where they went wrong.

It has worked perfectly fine with compiled languages until someone had the idea to use V8 outside of the browser.

In fact it still does, I only use node when forced to do so by project delivery where "backend" implies something like Next.js full stack, or React apps running on iframes from SaaS products.
