Amazon's Alexa might become your personal Einstein

So do Amazon, Apple, Alphabet and Microsoft -- and each is working to make its voice assistant your personal Einstein of choice. Amazon recently enhanced its efforts by nabbing an AI expert from eBay, The Wall Street Journal reported Friday. Hassan Sawaf is now Amazon's director of artificial intelligence, focusing on "the user experience for users of Amazon's search capability across all products and businesses," according to Sawaf's LinkedIn page. The Journal was one of the first to spot Sawaf's updated responsibilities on LinkedIn. "eBay has wide and deep capabilities in AI across the technology organization, and recently completed two acquisitions ... that contribute tech and talent to our AI and machine learning/machine translation capabilities," an eBay spokeswoman said in an email.
