Kind of disappointed with this article. I thought it would have more practical advice vs. just defining categories of learning (i.e. incremental, transformational) and talking about the need for learning. On this topic, a great read is Scott Young's "Ultralearning" https://www.scotthyoung.com/blog/ultralearning/. Well-researched, practical and the author has been successful following his own advice. Highly recommend.
Highly recommend Dmitri Fontaine's book "Mastering PostgreSQL in Application Development". Really helps emphasize how you can leverage the power of SQL to minimize all the Python / Panda steps to get the same result.
