For the record, as one of the developers on the Rust project: we consider that kind of over-the-top evangelism counterproductive and unwelcome. Note that in the talk that inspired this news, I specifically said that I wasn't there to push Rust, just there to explain how I'm working to make Rust an option for more people and projects.
Even if you want people to use more Rust, that kind of aggressive evangelism doesn't serve you well, and people find it off-putting.
