Rust isn't a one true language, no one necessarily needs to learn it, and I'm sure your preffered language is excellent. C and C++ are critical languages with legitimate advantages and use cases. Don't learn Rust of you aren't interested.
But Rust, its community, and language flame wars are separate concerns. When I talk shop with other Rust people, we talk about our projects, not about hating C++.
So don't use it. Rust is not intended to be used by everyone. If you are happy using your current set of tools and find yourself productive with them then by all means be happy with it.
You’re expressing the same attitude here, just in reverse. Some users not thinking highly of C++ doesn’t make Rust a worse or less interesting language.
