It's politically unacceptable to say so, but some human cultures are clearly worse than others, and yes, I expect there probably is a best culture. I wouldn't begin to guess at which one that is, but I would take people seriously if they're saying that a particular culture has got particular things right and other cultures can learn from that. The problem with imperialism was less the culture and more the exploitation and theft, which is not really relevant to the programming language case.
There is probably not a best culture (though there are definitely bad ones), just cultures that are further down the tech tree and therefore can out compete other ones. The same is true with programming languages.
