Partha Mukhopadhdyaya is an expert on cities, having studied them in multiple countries including China and India. He also happens to serve on our scientific advisory board. Mint carried the first part of an interesting discussion with Partha on cities. When we talk about the insights from big data for cities, we naturally get slotted into the data for “planning” box. But I’ve always been wary about planning and also talk about experimentation using near-real-time and low-cost feedback.
