There isn't a lot of good software written in Rust, open source or not. It's a lot of small and half-finished stuff here and there. The actual software out there is the ultimate, unforgiving, unfraudable review of a language, not what people say.

Developers seem to like Rust (or at least pay lip service). It's understandable. We are all suckers for a golden hammer. Rust promises no data races, no dangling pointers, high performance, and best of all it can run on numerous targets, making it a contender for The Last Language you have to know.

But you don't judge a restaurant's performance by the holiness of the chef's choice of tools in the eyes of other chefs. What is the most profitable piece of Rust software or the piece of Rust software that the most people depend on? If it wants to be taken seriously at the systems programming table, then we should see the Unix coreutils written in Rust (with all the command line flags working exactly the same way). Come on, replace GNU. You say you can do it faster and safer than everyone else. Let's see it.
