Innovation wants and needs
That's where I learned the difference between a WANT and a NEED. I was reminded of this concept when reading Tim Kastelle's blog about Flying Cars. Paul Krugman and Charlie Stross (one of my new favorite Sci-Fi authors) were talking about the lack of flying cars. Tim wonders if the lack of flying cars demonstrates the difficulty of disruptive innovation and the tendency for innovators to extrapolate current ideas into the future, rather than dream up completely new ideas. For example, why would we need flying cars if we could simply teleport everywhere? Rather than extrapolate existing technologies into the future, we innovators should drop back and solve for the bigger problem.
Another fact that goes unstated: we've had flying cars since at least the 1950s. It's not as though we don't have the TECHNOLOGY to create a car that can fly and then drive safely on the ground. A quick Google search produced this humdinger: http://articles.nydailynews.com/2010-06-29/news/27068585_1_faa-approval-terrafugia-transition-converts. No, the real challenge in this case isn't technological, it's structural. We simply don't all have runways out in front of our houses, and our neighborhoods are cluttered with a lot of low hanging trees, wires and other impediments to easy flight. Additionally, flying cars are inefficient and inexpensive. Krugman can have his flying car anytime he wants. It's just that most of us won't make that decision now, and probably won't until the design of cities and suburbs is radically altered.
Further, though, is the deeper consideration of wants and needs. While I may desperately "want" a flying car, deep down I know I don't really "need" a flying car. I can get back and forth to work and to most of my activities fairly efficiently without a flying car. That's the difference between an interesting idea and a disruptive innovation - wants and needs. We all have wants, some of which we may choose to fulfill. However, we all have needs that demand immediate attention. Good innovators understand the difference between wants and needs, and solve for the needs. Inventors, like the individual who created the latest in a long line of flying cars, are solving for the wants of a few very rich and eccentric individuals.
We innovators are often guilty of glibly tossing around words like "wants" and "needs". We need to understand the difference, and this is clearly a difference with a distinction. Wants are interesting and may lead an innovator to potential value, but are often not deeply rooted or key to a person's life. Additionally, wants often don't scale, that is, they aren't shared by a significant number of other people. Needs, on the other hand, are more immediate, more closely felt and more likely to be shared. Innovators must do a better job distinguishing between wants and needs.
