Personally I would say all the dynamic scripting languages, while they shouldn't "die", should stop focusing on adding new features and focus on the other things that will enhance the value of the language as it exists. This isn't criticism of those languages; it's a compliment! They've all hit maturity, in my opinion. That's a good thing. But I think their developer communities still sometimes don't act like that's the case, to their detriment.
