Rust has had channels since before Go was even publicly announced. Remember that Rust, like Go, was inspired by Pike's earlier language Limbo, which uses CSP. https://en.wikipedia.org/wiki/Limbo_(programming_language)

Rust has had OS channels since forever, and async channels for 5 years.

Rust has changed a lot in the past 5 years, people just haven't noticed, so they assume that Rust is still an old outdated language.
