If what determines the value of a language libraries (which makes no sense to me at all, but let's play your game), then it is one more argument against Python. You don't need FFI to use a Fortran library from Fortran, and I (and many physicists) have found Fortran better suited to HPC than Python since... the day Python came to existence. And no, many other scripting languages have wrappers, and no, scientific computing is not restricted to ML which the only area Python can be argued to have most wrapper libraries to external code.
Language matters, and two-language problem is a real problem, and you can't make it go away by closing your ears and chanting "doesn't matter! doesn't matter!"
Julia is a real step toward solving this problem, and allows you to interact with libraries/packages in ways that is not possible in Python + Fortran + C/C++ + others. You are free to keep pretending that problem doesn't exist.
You are making disparaging and hyperbolic claims about hyperbolic claims without proper attribution, and when asked for source, you cry foul and sadly try to appear smart by saying "you're acting dumb". You should take on your advice and instead of "acting dumb", explicitly cite what "promises" or "bombastic claims" you are referring to. This is what I asked you to do, but instead of doing it, you are doing what you are doing, which is interesting.

The fact that you can use those nice numerical and scientific libraries from the language that had also tremendous amount of nice libraries from other domains, wide and good IDE support, is very well documented and has countless tutorials and books available... is an argument against that language? Because you can easily use Fortran code in Fortran?
Nice.

Wow. Didn't know that.
> And no, many other scripting languages have wrappers,
Always less complete, less documented, with less teaching materials available etc.
But sure, many other languages have wrappers. Julia for example wraps Python API.
> and no, scientific computing is not restricted to ML
Never said it is. I don't do ML, by the way.

Yeah, yeah. My claims on marketing like "Julia writes like Python, runs like C" are hyperbolic and require explicit citation, even though everyone that had any exposure to this language knows such and similar catch-phrases.
Look, you like Julia, good for you. Have fun with it.
