Apple hires Google's former AI leader John Giannandrea to boost Siri

Google's former head of artificial intelligence John Giannandrea is joining Apple in an effort to improve the firm's voice assistant. Mr Giannandrea, a machine learning expert who joined Google in 2010, will report directly to CEO Tim Cook, it has emerged. The Scottish born specialist announced that he would be stepping down from his role at the search engine earlier this week. It is hoped his expertise can be used to make Siri smarter, as the pioneering software continues to lag behind newcomers from rivals Google and Amazon.
