Joel Selanikio: The surprising seeds of a big-data revolution in healthcare

Collecting global health data was an imperfect science: Workers tramped through villages to knock on doors and ask questions, wrote the answers on paper forms, then input the data — and from this gappy information, countries would make huge decisions. Data geek Joel Selanikio talks through the sea change in collecting health data in the past decade — starting with the Palm Pilot and Hotmail, and now moving into the cloud. (Filmed at TEDxAustin.)
