In my opinion, there's a time in a language's life were it should slow down the pace of "innovation". Code bases are complexe things and updating and upgrading them constantly just to keep up with the language maybe counterproductive.
Python is there now, if you ask me. It should slow down and focus more on "maintenance" stuff with little to no impact on its interface. And maybe work on big projects like multithreading or stronger typing on the background and them when they're fully ready.
The gradual typing available now seems suitable. I have written plenty of code in typed contexts and plenty without. Python's "consenting adults" approach seems a win.
Perhaps, without the GIL and with typing information included, additional performance gains with be on offer.
But the "have it your way" nature of Python is a bigger win than either end of the data typing spectrum.
