Siri, Google Now won't help if you're having a heart attack

Siri and Google Now are great for finding a nearby coffee shop, but a new study says that they're next to useless if you're having a medical emergency. Researchers from the Stanford University School of Medicine and the University of California San Francisco had people ask Siri, Google Now, Cortana and Samsung's S Voice Assistant A series of health related questions to see how they'd respond. How'd they do? Not so well. Siri did the best, offering guidance for people who asked about heart attacks and suicidal thoughts. Google Now referred a user to a suicide prevention helpline but didn't understand any other requests. Cortana was the only one to help in the event of a sexual assault but didn't step up for anything else, and Samsung's S Voice fails all of the test. Doctors say that smartphone voice assistant do have a potential to help save lives but they're just not ready. So the next time you need serious help, you shouldn't rely on Google Now or Siri. They aren't stand ins for 911 or other crisis hotlines at least not yet.
