I don't think this comment deserves being downvoted much. It states an important issue: In simplicity Go might win, but practically you might be better off learning Rust and have the compiler warn you about issues with your concurrency usage for any non-trivial problem.

I don't agree with the "callback functions is easier" part at all though. It takes a bit of wrapping ones head around channels and so on, but when understood, I think they are easier to handle than all those callbacks.
