Doesn't matter. Languages do not matter, ecosystems do, for they determine what is practically achievable.
And it doesn't matter that Python ecosystem relies on huge amounts of C/C++ code. Python people made the effort to wrap this code, document it and maintain those wrappers. Other people use such code through Python APIs. Yes, every language with FFI can do the same. For some reason none achieved that.
Even people using Julia use PythonCall.jl, that's how much Python is unsuitable.
> What promise are you referring to? Who promised you what? It's a programming language.
Acting dumb is poor rhetorical strategy, and ignores such a nice rhetorical advice as principle of charity - it is quite obvious that I didn't mean that programming language made any promise. Making a promise is something that only people can do. And Julia creators and people promoting it made quite bombastic claims throughout the years that turned out to not have much support in reality.
I leave your assumptions about my age or other properties to you.
