This lines up remarkably well with something I've thought about myself. People often argue about what the "best" first programming languages to learn is. I think it depends on what your goals or interests are:

1. Interested in math and computer science? Start with Scheme. 2. Want to be an engineer? Start with C. 3. Want to develop a product (or just general interest)? Learn Python.

These categories line up precisely with the article's three tribes: Mathematician/poet, hacker, and maker.
