When a CIA-backed venture capital fund took an interest in Rana el Kaliouby's face-scanning technology for detecting emotions, the computer scientist and her colleagues did some soul-searching - and then turned down the money.

Rana el Kaliouby, CEO of Affectiva, demonstrates their facial recognition technology. Recent advances in AI-powered computer vision have accelerated the race for self-driving cars and powered the increasingly sophisticated photo-tagging features found on Facebook and Google.
