A guy who thinks machines can prevent crime, another who thinks machines could destroy humanity and a machine-learning algorithm outsmarted by squirrels. Listen, decode and decide: Is the decisive machine evil?

Produced by Marketplace in partnership with Tech Insider, Codebreaker is a new podcast that dares to ask – and answer – the fundamental questions about technology that consume us every day. In season one, we’re starting with three deceptively simple words: Is it evil? In each episode, host Ben Johnson will apply this question to a different technology. 

Codebreaker isn’t just the name of our podcast, it’s also a way to listen. Each episode contains a hint to to help you immediately unlock the next installment and ultimately the entire season.
