How to Make Sure Your Robot Doesn't Become a Nazi

On Wednesday, when Microsoft had a much rosier view of humanity than it does now, the software giant released a "Millennial chatbot" to Twitter named Tay. She was supposed to mimic 18-to-24-year-olds, learn from her interactions, and develop a personality like her peers over time. This went exactly how you would've expected it to. Like most 19-year-olds on Twitter for 24 hours with no supervision, Tay had become a white supremacist Holocaust denier who believes that "Ted Cruz is the Cuban Hitler." Microsoft had to take the thing behind the server racks and shoot it Thursday morning.
