In a world where AI supposedly can write in any language, Go is much better choice than TypeScript. Imagine contemplating for more than a few seconds a choice between simple, fast, cross-compilable language, and a TypeScript -> JavaScript -> Interpreter -> JIT stack.
If you don't know Go, it's more efficient to learn it than to waste the hardware resources of thousands to stay within JavaScript.
