The author actually likes Go:
"Update 2: If you’re coming to this blog post from a compendium titled “Go is not good,” I want to make it clear that I am ashamed to be on such a list. Go is absolutely the least worst programming language I’ve ever used. At the time I wrote this, I wanted to curb a trend I was seeing, namely, overuse of one of the more warty parts of Go. I still think channels could be much better, but overall, Go is wonderful. It’s like if your favorite toolbox had this in it; the tool can have uses (even if it could have had more uses), and it can still be your favorite toolbox!"
