Things that people thought not possible when they were proposed and blown off become enormously successful. There are a lot of ideas that never succeed - but we all know the crazy ideas that did - who would have thought 30 years ago that people would pay $4 for a cup of coffee - but today, we have 20,000 Starbucks stores around the world. A group of prospective investors once remarked that "Google" was the "balloon company." The point is, don't rush to pooh-pooh something you don't understand or aren't willing to try - it could be something that changes the world.
