I am not saying that safety culture is irrelevant, not at all. I am saying that if the advantage of Rust is the culture that emphasizes safety (or rather memory safety, if the Rust community cared about safety in general cargo would not exist in this form) then that is a weak argument.
I don't think 10 years ago there was a lot of Rust used, so I am not sure how relevant it is that 1.0 was released at this time.
The culture of Rust is pretty uniform both in terms of convention (lots of good examples to learn from) and automated tooling (eg cargo clippy can fix many constructs into cleaner versions).
But sure, ultimately any code you see is limited by the talent of the author. However the safety of that code is not - it’s limited by how many unsafe blocks they wrote which you can actually grep for.
