Americans have big hopes that Big Tech can improve health care

People are bullish about the role big tech can play in health care. In a PwC survey, majorities said they’re at least somewhat confident tech companies will be able to: improve patient satisfaction, reduce costs, simplify health care, and make personal health care information more accessible to patients

Yes, but: It hasn’t happened yet. The most significant progress so far would be on that last front, making personal health data more accessible — that’s where Apple is focusing a lot of its health care energy, and the early reviews are generally pretty positive. But even that is still in its early stages.
