What happens when the Fourth Industrial Revolution collides with the need and desire to improve the state of the world? To be more specific: What impact will artificial intelligence (AI) have on the social sector? The answer depends on the reply to a bigger, deeper question: What ultimately does AI need to solve?

Actors in the sector are expected to ensure that people create and share resources equitably or fairly to the broadest extent possible.

A spy movie with its paraphernalia of cool gadgets and technologies has always enticed audiences. In these movies, we have seen the use of a polygraph to detect if somebody is being truthful or not. Needless to say, polygraph is a multi-billion dollar industry and plays a crucial role in crime adjudication. Polygraphs do not have any "intelligence" built into them.

Marketers have plenty of ways to measure video campaign success, but artificial intelligence is uncovering new methods for determining whether the dollars you're spending are being applied optimally. That's what video insights company YouFirst is offering, and a recent study of one of its clients, spanning 13 video campaigns over two years, is revealing. Even with the latest and greatest analytics tools at the brand's disposal, AI and emotion tracking are opening up new insights. More importantly, AI is showing where to make changes to a campaign so it hits its exact target market -- and when to pull the plug. YouFirst works by allowing a focus group of video viewers access to the content through its player, which -- with permission -- monitors the facial expressions of the consumer via a webcam.
