>It’s made absolutely no negative difference, as we’ve seen in the real world in the last 60 days since the merge.

The rust code is not yet in a stable release, and CC only switched to it in the latest version, so there's not been 60 days of widespread battle testing yet, so i don't see how we could possibly say it will have no negative difference. It hasn't, because nobody is using it yet. It still might.

>Literally who cares what language a JS toolset is written in?

I don't care what language it's in, but i do care how it is written and maintained. I'm not going to trust my projects to a runtime that was written by an LLM in two weeks with practically no human review
