Researchers Feng Liu, Yong Shi and Yin Liu carried out tests throughout 2016, which ranked Google's AI IQ at 47.28, just shy of the average IQ they found for a human 6-year-old: 55.5. Siri's IQ fell well below at 23.9, which was also lower than Microsoft Corp.'s (MSFT) Bing and Baidu, at 31.98 and 32.92, respectively.
