Does anyone else have muddled together in their mind Golang, Rust, and Dart, as three almost cult-favorite languages of similar popularity and unclear differentiation? Here's what I found; someone fill me in or prove me wrong, please!

Golang is easy, Rust is hard, Dart is made for web. Dart and Go were both Google products, though Dart is open now. Go and Rust hit heavy on the low-level performance thing. Rust has the most compelling Free Software story of the three, if tech ethics matter to you.
