Rust is a great language, I agree. It does solve a lot of problems, sure.
But why "it's written in Rust" or "it's a Rust app" should always be the selling point for any modern app? Seriously. There's no need for it. Feels like people are trying to use that to say "look how cool and safe my app is".
I don't remember anybody ever saying "my app is written in C", or "it's a Python app", and expect "that's the seller right there".
Well, maybe the exception is Java, when people say "it's a Java app" to mean "it's bloated and will eat your RAM for breakfast".
