You could compare it with 3D. Many people fall in love with the idea of "3D" when they see these beautiful renders all over the place....artists that make things look easy but when you sit down to do it yourself, you realize just how difficult it can be every step of the process. I do web design/dev for a living and have since the late 90s. It's like anything else, things come together the more you do it but it's also a continual learning process as technology and code changes. I remember when folks started migrating from tables to CSS for layouts....major headache.
