CARY – There's a lot of buzz around artificial intelligence (AI) at the moment, specifically as it relates to the Internet of Things (IoT) and its growing role to organize and analyze big data. But is the combination already outperforming humans? That was the big question when Internet of Things users group RIoT put on its 28th RIoT event, in partnership with SAS, on Tuesday night in Cary. Around 200 packed into the SAS Executive Briefing Center to catch a lineup of industry leaders tackle the topic of AI and machine learning, and the hotbed question of the day. "In certain areas, definitely," responded Phillip Simulis, CEO of Virginia-based Simtelligent, who was among the speakers, to the big question.
