"""There is no rise. Not any more. At best, it's a plateau, and in my opinion, all dynamically typed languages except Javascript are on a straight decline curve, slowly being replaced by statically typed languages."""

This sounds like wishful thinking. (Your wish, apparently... certainly not mine. :-) I have seen no evidence that Python is on the way out. If I look at the languages asked for in HN's "Who's Hiring" thread, Python is #1. Even so, there are dynamically typed functional languages, like Clojure and Elixir, that are definitely on the way up.
