The narrative usually goes something like this: a naïve scientist invents a clever piece of technology designed to improve the quality of life in the developing world, only to be shocked and horrified when it is not wholly embraced by the people it was designed to help. Of course, such characterizations could not be further from the truth. Many scientists, especially those working on technologies for the developing world, take on challenges precisely because of their desire to address human-level complexity. The fact that difficulties arise on occasion comes as neither a surprise nor a disappointment to them. It’s just part of the job.
