Ten years ago, the idea of tracking your footsteps or your heartbeat was weird. Those dedicated to the pursuit of quantified self knowledge proselytized in TED Talks, while journalists attended conferences and reported on the strange new trend.

It is not uncommon to hear retirees comparing or boasting about their step count for the day. The quantified self is ascendant.
Now, as artificial intelligence’s relentless advance continues, researchers and technologists are looking for ways to take the next step—to build AI health coaches that sift through health data and tell users how to stay fighting fit.
