This is a nice taxonomy of knowledge. I tend to feel that discussion in development circles revolves too much around the newest technologies (long before they've proven themselves), and not enough around the stable mainstays of the profession. This is fine for seasoned professionals, but lulls newcomers into investing into niche tech, like Meteor or the blockchain. That time is probably better spent learning a text editor, GNU/Linux, Postgres, and Python. I guess that's the lesson: the technology that's most discussed is not necessarily the tech that's the best to learn.
