I agree that dependencies are a liability, but, sadly, "batteries included" didn't work out for Python in practice (i. e. how do I even live without numpy? No, array aren't enough).

To the extend that Python is indeed "batteries included," that seems true. But just how "batteries included" is it? I'd argue that its batteries are pretty limited. Exhibit A: everybody uses the third-party requests instead of the stdlib urllib. Exhibit B: http.server isn't a production-ready webserver, so people use Flask or something beefier.

I'd contrast Python with Go, which has an amazing stdlib for the domains that Go targets. This last part is key--Go has a more focused scope than Python, and that makes it easier for its stdlib to succeed.
