You're free to structure code in and around goroutines however you like. No one's forcing you to spray this all over your codebase. Feel free to implement work queues, or the actor pattern, or whatever. No one's forcing you to use whatever frameworks or libraries or patterns; that's all you.

So much of all of this is weirdly entitled. Languages that do things differently exist: Erlang, Pony, Rust. They all make wildly different tradeoffs than Go does, not better, not worse, different. If you think they're better, use 'em. Let your better software win in the market. These weirdo polemics just fan language flamewars.
