Microsoft's A.I. and research chief Harry Shum is leaving

Microsoft said on Wednesday that Harry Shum, the executive vice president in charge of its artificial intelligence and research group, is leaving the company in early 2020. Kevin Scott, the company's chief technology officer and formerly a LinkedIn executive, is taking on Shum's responsibilities in addition to his own. It's not clear what Shum will do next. Shum has been a figurehead in the more integrated approach to research that has taken hold at Microsoft during the tenure of CEO Satya Nadella, who replaced Steve Ballmer in 2014. His group has been one of the most prominent technology research institutions outside academia, alongside the likes of Google parent-company Alphabet and Facebook.
