I overall agree with you and there is no reason to rush switching languages for already established projects, but not even for new ones. But I don’t think that this quoted part is really true about the Rust community. Sure, it has a very vocal minority you hear the most which might fit your description (it’s always those we see first), but I find the more general community very well-versed in low-level programming, more often than not having a strong C++ background and/or some advanced FP knowledge, which is great. I regularly visit r/rust even though I don’t use the language too much, simply because the quality of discussion on certain issues is very high.
