I have a bit of a theory on that, which I bet will be a bit unpopular but is based on some social things I have seen. A dynamic language gets popular[1]. As more people show up, they want to bring their way of doing things (e.g. "prototypes are stupid, we need classes") instead of fully adopting the language. Improvements are cool but some of the changes alter things in a fundamental way (e.g. dynamic to static). Sometimes it leads to second systems (e.g. Objective-C to Swift) and is often accompanied by "the need to grow up". Then we get a new language. 1) could actually be any language that doesn't fit the mainstream mold
