Technologists are building computer algorithms that will soon match something that has, until now, been uniquely human: The ability to recognize a person as soon as they walk into a room, even if they’re not looking right at you. There will soon be a day when your home knows exactly who you are. We explore the potential of 3D scanning technology, and the ethical questions surrounding its adoption, in this episode of “The Future According to Now”, a podcast from Atlantic Re:think, the branded content studio at The Atlantic and Fidelity Investments.
