The success of "modern" CLI tools written in Rust (uv, oxlint, turbopack) show there's a clear demand for faster tools in general.

Also, faster feedback loop is crucial for AIs, so I guess this makes sense.

What they show is that JavaScript should never have left the browser into the backend.

Don't rewrite into Rust, Go, Java, .NET, Zig, Odin, whatever.

Start with them directly.
