I felt the same with components. I was using encapsulated components with internal state and defined interfaces more than two decades ago and it was old technology even then. The web is a funny place, they grab something and claim it's revolutionary but often forget to mention where it came from. It's not a bad thing but I have often joked if you want to see what is considered state of the art in Year X go see what the academics where doing in (X-20) years.
