Developers Daniel and Aimee Hendrycks conducted a Personal Assistant Artificial Intelligence Strength Test (PAAIST) They asked Apple’s Siri, Googles Google Now, and Microsoft’s Cortana a series of “60 randomly generated, hard questions” None of the three did particularly well. Google Now answered 33% of questions correctly, followed by Siri at 25.8%, and Cortana with 11.7%. Cortana scored only 700 out of a possible 6,000 questions. Siri scored 1,550 out of 6,500, but unlike Cortana, Apple’s personal assistant didn’t know who wrote The Girl with the Dragon Tattoo.”]
