It is not important to just push technology into rural areas. The most important thing is the final application and the model to make the deployment of the technology economically viable. If we do not have a model for that, once the brain behind the project disappears, the project and the technology dies. The blame then, I believe, is fixed on technology!! What a shame that is... The failure of human foresight blamed on the laws of science!!!
I do believe in the bottom-up approach that a lot of people here are advocating.. However, the research community often uses the bottom approach to come up with novel observations for research papers and in the process the finished application just gets forgotten... And more often than not, one success story covers up for hundreds that were not done right (of course I exclude those that didnt work right.. beacuse if everything worked, it wouldn't be called research, right??? )
