Go and Javascript.

I’m going to go out on a limb and predict that Python is being replaced by Go. I don’t have a lot of information to back up this prediction except that most of the positive articles I read about Go are written by Python developers, and a lot of them say that they are now actively migrating their code base from Python to Go. I don’t see as much enthusiasm for Go from developers using statically typed languages, probably because of Go’s antiquated type system (which is still a big step up from Python, obviously).
