But isn't this true of all technologies? I know plenty of people who are amazing Python developers. I've also seen people make a huge mess, turning a three-week project into a half-year mess because of their incredible lack of understanding of the tools they were using (Django, fittingly enough for this conversation).

That there's a learning curve, especially with a new technology, and that only the people at the forefront of using that technology are getting results with it - that's just a very common pattern. As the technology improves and material about it improves - it becomes more useful to everyone.
