There is a popular myth that great ideas are a dime a dozen (see here, here, and here). I don’t know what a great idea is. Is a Dick Tracey watch or a nuclear powered rocket a great idea? No, not if you don’t know how to implement them, then it is just a fantasy and unless you have plot with it, it is not even a good fantasy story. However, I do know what a great invention is and they are not a billion dollars a dozen. A great invention takes incalculable intellectual skill, years of training, years of hard work, and significant resources.
