Who resigned after colleagues' firings. Apple has hired former distinguished Google scientist Samy Bengio, who left the search giant amid turmoil in its artificial intelligence research department. Bengio is expected to lead a new AI research unit at Apple under John Giannandrea, senior vice president of machine learning and AI strategy, two people familiar with the matter said. Giannandrea joined Apple in 2018 after spending about eight years at Google. Apple declined to comment on Bengio's role. Bengio who left Google last week after about 14 years said last month he was pursuing "other exciting opportunities". His decision followed Google's firings of fellow scientists Margaret Mitchell for taking company data and Timnit Gebru after an offer to resign.
