Artificial intelligence has had a bad rap (see: Terminator), and public confidence has waned. Would you trust a machine to diagnose you? Medical professionals today faced off against health firm Babylon's'Check a Symptom' app feature, in a bid to find out who's best equipped to triage patients: man or machine? The challenge saw Professor Irwin Nazareth, former head of primary care at UCLH, examining patients with the help of either: (1) one of Britain's most senior A&E nurses, (2) an Oxford-educated Junior Doctor, or (3) Babylon's'Check' feature. It turns out that that the app came to "the same accurate assessment" as both the nurse and junior doctor, but faster, and at no cost.
