I'd rather learn to draw gesture (which is what is described even if they didn't know the name for it) and simplifying from Glenn Vilppu or Steve Huston, personally, and you don't need mystique about the class like this article tries to evoke. You can find both at New Masters Academy (NMA.art) for a super reasonable monthly cost - sort of like an art lessons netflix. If your goal is to draw like picasso you need to be where he is at 15 before you understand what you're simplifying. Even after you take apple's class you'll have concepts but you won't have thousands of hours of practice that actually using any of those lessons requires.
