Um, I have to disagree with your points on Go/Rust. You make Rust sound like the easier language, when in reality it just isn't.

And what concurrency thing are you talking abou with Go? Goroutines/channels are pretty decent in Go.

I probably wouldn't tell anyone to learn Rust unless they truly desired it specifically for a certain task.

Rust is also harder to get into because everything you want to do requires a package, but on the other hand Go is much easier because of its expansive standard library.
