Could Cortana 2.0 be a chatbot? Microsoft's new AI chief hasn't ruled it out

Cortana has a new boss, and he has a problem: If Google's turning its Google Now digital assistant into a chatbot, should Microsoft do the same with Cortana? In 2014, Microsoft first unveiled Cortana, the digital assistant within Windows 10. Interacting with Cortana was simple: You asked a question, she responded. In the last few months, however, Google's Assistant has offered an alternative: a chatbot that interacts with users via an ongoing stream of text and images. In an interview with PCWorld, Shum said he hasn't ruled out adding a Cortana chatbot to its roster of digital assistants.
