You do need design patterns in Go. A prime example: the interface that Sort() requires is basically the Strategy pattern. You need it in Go because the language is missing generics. There are many other examples.

In that message, Rob Pike misunderstands what the visitor pattern is for. Go's "type switch" is just chained Java instanceof. Java still benefits from the visitor pattern for (e.g.) compiler transformations, even though it has instanceof.

This is one of the more troubling aspects of the parts of the Go community that I am exposed to--aggressive insularity. It's perhaps cyclical--in the past I've made similar criticisms of Node, and did of Ruby before the hype died down and the more aggressively enthusiastic people calmed down or moved on--but it's kind of a pain in the rear at present. That said, Go's deification of a single individual is unique to me; of Matz, Guido, Bjarne, Gosling, or Rasmus, I don't know any who are quoted as if it's by itself persuasive. What Rob Pike says about things is not necessarily correct--and sometimes it's not even accurate--but seems strangely, to Go advocates (as separate from "Go users"), to immediately enter a sort of canon to be trotted out at every opportunity.
