Cardiologist Eric Topol explains how artificial intelligence can make doctors more humane

Many doctors take a very conservative view when it comes to new technology. But Eric Topol, a cardiologist and author, is a self-described "digital geek," a long-time proponent of using the latest gadgets in medicine. He even upgraded his black bag to include wearables and connected medical devices, rather than the old analog blood pressure cuffs and stethoscopes. So for technology companies like Apple, Alphabet and Microsoft, Topol is an important ally as they get deeper into the medical sector. It can't hurt that he's one of the most influential doctors on social media, with over 150,000 Twitter followers.
