> The future of Python's main open source data science ecosystem, numfocus, does not seem bright. Despite performance improvements, Python will always be a glue language. Your first sentence is a scorching hot take, but I don't see how it's justified by your second sentence. The community always understood that python is a glue language, which is why the bottleneck interfaces (with IO or between array types) are implemented in lower-level languages or ABIs. The former was originally C but often is now Rust, and Apache Arrow is a great example of the latter. The strength of using Python is when you want to do anything beyond pure computation (e.g. networking) the rest of the world already built a package for that.
