If you have a green field, by all means write it in rust. If you have a brown field, and a functional profitable system, rewrite the parts that need rewriting in the original language, whatever that is, and carry on. Make your systems better in small measurable ways, with the language you know and a team you trust to implement it all. Anything else is a wasteful religious argument.

I don't see any reasons to use Rust when your team successfully shipped and is confortable with C#/Java/Go ect ...

If anyone one comes and tells me we need to rewrite in a new language from any of those modern languages, other than you are dealing with something cannot wait for GC.

That is a signal that person is lacking purpose in their job or life.

GC pauses are not the only reason. At the very least, raw compute performance and lower memory usage are also valid reasons in some contexts.
