In five years, machine learning will be a part of every doctor's job, Vic Gundotra says

When Vic Gundotra left Google in 2014, he thought he might retire, forever. But a lingering interest in wearable technology and machine learning led him to AliveCor, which lets users monitor their heart health from their smartphones. Diving back into the fray of tech, Gundotra is now convinced that the potential of wearables and machine learning is just starting to be unlocked. AliveCor's portable EKG sensor, Kardia, alerts users if their heartbeats are irregular -- and now, the Mayo Clinic, an AliveCor investor, has begun identifying other signals in an EKG reading that a human might miss. "No human doctor can look at your EKG and tell you with a high degree of accuracy what your potassium level is," Gundotra said.
