Maybe it should have been titled "why some experts think teaching is easy, and why they're wrong". As in, an expert might naively feel like they can teach a subject well simply because they know it well. However, the article shows why that intuition doesn't actually work. If, on the other hand, you want to put significant time into learning how to teach, then I imagine anyone can be a good teacher. I found the article itself fascinating, because I've gone through that experience myself. It may be obvious to some, but for me it was neat to hear that the realization I came to in my teaching is a common one amongst people who have spent lots of time learning and not a lot teaching.
