Synced Google AI Assistant Smartest in Human IQ Tests

They may live in our smartphones, but just how "smart" are Siri, Cortana, and other digital voice assistants? Researchers from the Chinese Academy of Sciences used human IQ tests to find out. The results of their study were published this September and ranked the 2016 edition of Google's generically-named "Assistant" at the head of the class with an estimated IQ of 47.28. Baidu's Dumi came in second at 32.92, edging Microsoft's Cortana (31.98). Surprisingly, Apple's Siri trailed the pack with an estimated IQ of just 23.94.
