Those 10 seem like a stretch. I think maybe 3 or 5 deserve to be mentioned as top thinkers. Does designing an app to clear fire hydrants from being buried under snow really deserve to be compared to a guy who did Tesla, Spacex, SolarCity and Paypal?
Surely they can do better. Google Glasses. Nope. I love Tony Fadell but an overpriced Thermostat & Smoke Detector does not make you a thinker. Musk should be there because he is involved in multiple disciplines.
