Sometimes the technology just doesn't want to show you what it can do. You have to keep pushing on it and asking the engineers over and over again to explain why we can't do this or that—until you truly understand it. A lot of times, something you ask for will add too much cost to the final product. Then an engineer might say casually, "Well, it's too bad you want A, which costs $1,000, instead of B, which is kind of related to A. Because I can do B for just 50¢." And B is just as good as A. It takes time to work through that process—to find breakthroughs but not wind up with a computer no one can afford. - http://www.inc.com/magazine/19890401/5602.html
