Since you have a rosy picture of Python, I assume you're young. Python has been mostly a fringe/toy language for 2 decades, until around ~2010, when a Python fad started not too different from the Rust fad of today, and at some point Google started using it seriously and thought they can fix Python but gave up eventually. The fad lived on and kept evolving and somehow found some popularity with SciPy and then ML. I used it in 90s a little, and I found the language bad for anything other than replacing simple bash scripts or simple desktop applications or a desktop calculator, and I still think it is (but sure, there are people who disagree and think it is a good language). It was slow and didn't have type system, you didn't know whether your code would crash or not until you run that line of code, and the correctness of your program depended on invisible characters.
"Ecosystem" is not a part of the language, and in any case, the Python ecosystem is not written in Python, because Python is not a suitable language for scientific computing, which is unsurprising because that's not what it was designed for.
It is ironic you bring up hype to criticize Julia while praising Python which found popularity thanks to hype rather than technical merit.
What promise are you referring to? Who promised you what? It's a programming language.
in the early aughts educators loved the shit out of python because "it forced kids to organize their code with indentation". This was about a decade before formatting linters became low key required for languages.

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.
