This is the most inspiring talk I have heard for ages: Anil Gupta: India’s hidden hotbeds of invention.
The TED summary just hints at what is being done: “Anil Gupta is on the hunt for the developing world’s unsung inventors — indigenous entrepreneurs whose ingenuity, hidden by poverty, could change many people’s lives. He shows how the Honey Bee Network helps them build the connections they need — and gain the recognition they deserve.”
One valuable comment Anil makes is that we often discard solutions to a problem because “they do not scale”. He reminds us that if people in a locality find a solution for an issue that works only in their area – that is enough for them. Probably we are better off with a million local solutions than one global solution. This is like Darwinian evolution; let’s develop what fits in each niche.
