I think the parent was speaking specifically about the language, not the ecosystem. More "if I open up this Python file, can I understand what it's doing," not "can I execute this application easily." I think Python is excellent at the former—Syntax is simple and explicit, "clever" code is discourages by both the language and the community. Packaging is a known pain-point in Python and does make the language less approachable. But beyond that I don't understand your criticisms. uwsgi, celery, nginx, RabbitMQ are all useful tools that are oftentimes used in web applications. What language are you using that magics away the need for tools like these? All these same tools or their equivalent still exist in the Rails ecosystem. I don't have much hands on experience with ML, so I guess I can't comment on that. Is there something about Python that exacerbates the issues you've laid out?
