There's a selection effect: people like me experience so much ambient hostility in society that we gravitate towards communities that welcome us and that already have people like us in leadership positions. So the correct metric is not % of all developers as a whole but just the ones involved in the Rust community.

The Rust community has many nonbinary and transgender people in it, and speakers are selected from the community. The selection process for RustConf is blind so the talks were picked for their merit: it just so happened that half of the speakers weren't cis.

> rust is a very unique community

Yes, this is true in my experience.
