While channels are awesome, and are a good pattern, what's important about Rust is that it lets you do channels, but if you need to share mutable memory for some reason, Rust still has your back in that use-case. We can guarantee no data races, even with shared mutable memory, at compile time. It's pretty huge.

That said, channels in Rust are also nice to use, and you shouldn't not choose channels. Rust just enables other use-cases too.
