This edition of the Sleepwalkers podcast looks at AI's growing power to "read" us--and investigates the sinister and the positive uses of the technology. Poppy Crum, chief scientist at Dolby Labs and a professor at Stanford University, is using advanced sensors and AI to capture emotional signals. From thermal sensors that track blood flow to CO2 monitors that detect our breathing rates and cameras that track microscopic facial recognition, it's getting harder to maintain a poker face in front of machines.
