I think the difference here is that the original motivation for choosing Go over Rust was that Go was easier to port TypeScript to.
LLMs change the calculus a lot, the result seems faster, and it's possible that the TypeScript team might want to change directions. It'd be a big deal, but I bet they'll at least discuss it.
There is a long interview with Anders Hejlsberg here https://www.youtube.com/watch?v=cywK3XYYJ2o&pp=ygUbYW5kZXJzI... where he talks about that, in short from what he said 1-2 months ago, I doubt that they will change directions.
