Python/JS/PHP/Ruby are still plenty popular... but the weight they are putting on "dynamically typed" is decreasing over time. Basically, all the dynamic languages are creeping towards the statically-typed side with various partial annotations and optional features. But there are no statically-typed languages I know of rushing to add more dynamically-typed support to their languages. If you draw all those language trends out, they don't meet in the middle; they meet solidly in the "statically-typed" area.

I phrased that carefully; obviously they aren't going to stop being "dynamically typed" under the hood. But, slowly but surely, those language's contribution to "dynamically typed" is decreasing, and I expect, will continue to decrease.

In another 20 years, I expect "dynamically typed" will be looked at as a complete mistake by the oversimplification process of history, as the number of people who were around when they were getting popular and understand why they were so attractive decreases. I do, myself; I experienced being liberated from some really, really crotchety languages by the freedom of Python 2.0, and I understand why the people of the time analyzed the programming landscape, and decided that the problem was "static typing" rather than "bad static typing", because there weren't any examples of good static typing. But now there are, and they aren't going to go away, and I expect that barring legacy languages, the choices in the future are going to be simple static typing like Go, complicated static typing like Rust, really complicated dependent typing like $LANGUAGE_YET_TO_BE_BUILT, and tiny languages like shell designed to never write programs in them large enough for typing to even matter.
