Sleepwalkers is now Kill Switch, where we explain the right now of living in the future. Everything from making money on saving fake baby animals to how you could get arrested by a police algorithm. Every Wednesday we talk to people to help us understand how our tech-focused society works …or doesn't work.

Were we sleeping when everything changed? Not if you listened to the first season of this podcast, because a whole lot of what we explored is now reality. Seems like the technologically driven future is already here. So we've decided to bring the show back -- with a new host, Dexter Thomas Jr and a new perspective.

On Kill Switch, we explain the right NOW of our super charged technological lives. Examining the ways we shape and are shaped by our ever-changing technology.

We explore the hidden role of cobalt in the A.I. revolution. The element is a key ingredient of lithium-ion batteries, which power everything from cell phones to laptops to electric vehicles. But the way cobalt is mined is troubling. New Yorker journalist Nicolas Niarchos takes us to the Democratic Republic of Congo, which accounts for more than 70% of the world's cobalt supply. There, he exposes child labor in the supply chain and reveals a new frontier of competition with China.

In this special episode, Oz and Karah examine our evolving relationship with the technology we create. Karah meets Jason Cohen, CEO of Analytical Flavor Systems, to see if his team can hack her taste preferences, and use AI to create a new flavor of beverage that she will love. Oz and Karah also look ahead to Season 2, previewing stories they are excited to report, including algorithms that promise to optimize end-of-life conversations. And they share highlights from conversations with guests from Season 1 who shaped their thinking about AI: Yuval Noah Harari, Siddhartha Mukherjee, and Regina Barzilay of MIT.

The rules are changing. At a time when technology promises to allow the lame to walk and the blind to see, we're forced to ask: what makes us uniquely human? In this final episode of Season 1, we speak with the so-called "sage of Silicon Valley," Yuval Noah Harari, about humanity's future. We try out technology that claims to deliver on a miracle, and we meet the source of several new innovations being created by people normally left out of the laboratory.  In this episode: Professor Yuval Noah Harari, Sebastian Thrun of Google X and Kitty Hawk, Bryony Cole of Future of Sex, musician Noe Socha, and Dr. Andy Schwartz of the University of Pittsburgh.  Special thanks to The Forward, and Make It All Work.

A.I. is already better than human doctors at diagnosing skin and breast cancer. And as machine learning advances, it's becoming able to decode more complex information, like brain waves and the human genome. A.I. is beginning to revolutionize medicine, and allowing us to see into the future of our bodies...but can we ever know too much about ourselves? What will happen when machine learning lets us open our own black boxes?

In this episode: Physician and author Dr. Siddhartha Mukherjee, Google X founder and Kittyhawk CEO Sebastian Thrun, Regina Barzilay of MIT's J-Clinic and CSAIL, Dr. Andy Schwartz of the University of Pittsburgh, Gill Pratt of the Toyota Research Institute.

War has been a driver of breakthrough technology for a long time. The first waves of artificial intelligence and even the internet came out of DARPA, a defense agency whose original mission was to keep the U.S. technologically ahead of the Soviet Union. But what happens when the battlefield is increasingly dominated by autonomous weapons, which don't require humans in the loop to shoot and kill? In this episode: Arati Prabhakar, former head of DARPA; Richard Danzig, former Navy Secretary; Paul Scharre, author of "Army of None"; and Jonathan Wilson, former Navy SEAL.
