The secret of innovation, Provide skills, not just finished technologies, is incredibly powerful because it creates lasting change. Skill gives people to make changes, but it also empowers them to engage their problems.
Technology only solves a specific problem. On the other hand, a skill allows people to develop solutions to an entire class of problems.
For example, giving a farmer a truck allows him to transport products and supplies. Using the same amount of money to teach people how to repair cars and fabricate parts does several things. First, more cars can stay on the road, and that provides transportation to more farmers (not just one).
Second (and perhaps most important), people can apply those mechanical skills to other areas. Now, they can build and repair pumps (for wells). They can create machines to grind grain and wash clothes.
A society changes once people have the confidence to create solutions. The people are no longer passive players, dealing with what they have been given. Individuals can look around at the problems and figure out what to do. Everyone benefits from a good solution. Plus, the innovative individuals have a chance to sell their product and services, which grows the local economy.
A piece of technology has a finite life; knowledge can be passed down infinitely. Giving things to people is a short term solution. We must find ways of closing the knowledge gap to create real, lasting change.
