Simplicity and Demystifying Technology

I was not only amazed at discovering the simple but uniquely powerful concept of Barefoot College. It is a college and a social research center in one of the poorest villages Tilonia, Rajasthan India. The endeavor started almost 30 years ago; creates self sufficiency among the rural folks; where villagers with primary education are working with computers, maintaining solar panels etc This is truly achieving simplicity; demystifying technology. Even though, I was proud of this fact but at the same time it created a deep sense of hollowness in me and my work. Is my work really valuable? Am I paying my dues to the society? Even though, my work may not value up to the mark of social contribution I would ensure I do a tad bit to contribute back to this society.
