I enjoyed this post about one team's transition from Scala to Go. I think it's about how discouraging cleverness is important in programming languages and codebases. I don't think this article is about Go. The point here is the Scala language (and a popular library) made it possible for the code to be opaque to his own teammates (who were also Scala programmers!). Choosing to use Go going forward is one possible conclusion. If the article said that they chose to use vanilla Java 8 instead, I think the takeaway would be the same.
