Mozart was recognized as a musical genius around age four, and was composing things as early as age four or five. Is this kind of knack for something common? No. Is it possible? Absolutely. For the most part, I agree with Mr. Miller. I don't think individuals who do not have years of experience should be releasing things like lecture notes or lecturing other individuals. Creating effects, on the other hand, is another matter. The reason I say this is because many of magic's creators are just that. . . creators. Many of them are not performers because they have neither the passion nor the knack for getting up in front of people and actually doing magic. If you have a creative brain and are able to innovate strong, new pieces of magic, even without having performed magic for ten plus years, to me that's valid. A good effect is a good effect, regardless of the age or experience level of the creator. Some people really are just gifted that way. It might take a performer to teach the effect to other performers, but that individual is still only teaching something that someone else created (examples that come to mind are things like Revolution, King Rising, and Kaos, which were not taught by the people that created them).
