It seems like artificial intelligence is everywhere these days — in our homes, in our cars, in our offices, and of course online. Government decisions, too, are being outsourced to computer code. In one Pennsylvania county, for example, welfare services use digital tools to assess the likelihood that a child is at risk of abuse. Los Angeles contracts with the data giant Palantir to engage in predictive policing, in which algorithms identify residents who might commit future crimes. Local police departments are buying Amazon's facial recognition tool, which can automatically identify people as they go about their lives in public.

What does all this mean for our civil liberties? And how can the public exercise oversight of a secret algorithm? AI Now Co-founder Meredith Whittaker discusses this brave new world — and the ways we can keep it in check.
