Why will TypeScript 7 make Node.js irrelevant?

In TypeScript 7, the compiler will be written in Go instead of TS. But the compiler will still produce JS code as its output and so Node.js is still relevant for running that JS code.

Or is there something else about TypeScript 7 that will make Node.js irrelevant?

The output would probably not be node, it would target the browser. TypeScript is the only real Node project worth a damn in open source.
