I think the comment isn't really about the technical merits, but more about the fact that Rust has gotten some major traction, not just in Mozilla but elsewhere.

Where else? Rust usage is quite small at the moment relative to Object Pascal and definitely to C++. The new language that's rapidly gaining marketshare is Swift, mostly because Apple's pushing it.

The most notable one I'm aware of is Dropbox, who are reportedly using Rust in production for some low-level parts of their storage platform.

Do you have a link to the reports? Python and Go seem to be used a lot at Dropbox. Blog post on their Go usage: https://blogs.dropbox.com/tech/2014/07/open-sourcing-our-go-...

I could only find two Rust repositories on their github page, both of which are library bindings forked from other projects, so that seems to indicate some Rust usage. But then again there are more Haskell repositories than Rust repositories: https://github.com/dropbox

They've talked about it on Reddit a lot. https://www.reddit.com/r/programming/comments/3w8dgn/announc...

Their Rust stuff is closed source, not open source.
