There's a phrase, "Fractals are everywhere" it is the title of a book. The book was not written by me; the phrase was not coined by me. I think that the phrase is correct, to the extent that if you go around and look at phenomena of every kind, you probably will find somewhere in a corner an aspect which is fractal. I think it is probably correct. In this sense there are fractals everywhere. Now, I don't think that those fractal parts are necessarily important. In many phenomena they're not important, sometimes because those phenomena are simple and very often because they're even more complicated than any fractal. But this fractality is not complication without rules. Fractality is a form of geometric complication with very specific rules, very strong rules; and disorder, chaos, complexity, call it as you wish, and is present in many places in a way which does not have any clear rules. So if there are fractals everywhere, it doesn't mean that fractals are important everywhere. And it is not only my caution that tells me that, but also my experience.
