Microsoft is launching a $25 million initiative to use artificial intelligence to build better technology for people with disabilities. CEO Satya Nadella announced the new “AI for Accessibility” effort as he kicked off Microsoft’s annual conference for software developers. The Build conference in Seattle is meant to foster enthusiasm for the company’s latest ventures in cloud computing, artificial intelligence, internet-connected devices and virtual reality. Microsoft competes with Amazon and Google to offer internet-connected services to businesses and organizations. The conference and the new initiative offer Microsoft an opportunity to emphasize its philosophy of building AI for social good.
