Uh, I think you're forgetting PHP. Not to mention Clojure is at least as popular as Go. Dynamic typing isn't going anywhere, desire for 'gradual typing' is a very niche but vocal desire in the dynamic language communities. It may lose some mindshare but there are a lot of options to lose that to these days since even the holdouts of 'annoying' static typing with terrible type systems like C++ or Java are making it more and more feasible to ignore/not specify the types in your code.
