Agree with the first statement but, not necessarily on the second.

People dismissed React for being "too new" or "the latest stupid shiny new framework" for a long time because they didn't understand it. But when I read about it for the first time, I understood the problem it was solving with the VDOM. It made perfect sense for me to start using it immediately because it quickly starts saving a lot of time formerly spent on writing DOM setting/resetting code and making sure it never breaks. It was something I was already thinking about: "how could I avoid writing all this tedious DOM manipulation code". And there it was, and I knew it would become big. It took a while for the rest of the world realize it, but eventually it caught on.

Sometimes tools pop up that make perfect sense. So you shouldn't dismiss any technology for its age, whether it's old or new.
