For my latest podcast, I read my Guardian Cities column, "The case for ... cities that aren't dystopian surveillance states," which was the last piece ever commissioned for the section. The Guardian commissioned the piece after reading my Toronto Life blurb about how a "smart city" could be focused on enabling its residents, rather than tracking and manipulating them. In the article, I revisit my 2015 Locus column on the idea of an Internet of Things that treats people "as sensors, not things to be sensed" -- a world where your devices never share your data with anyone else to get recommendations or advice, but rather, where all the inanimate objects stream data about how busy they are and whether they're in good repair, and your device taps into those streams and makes private recommendations, without relaying anything about you or your choices to anyone else. As I've often written, the most important thing about technology isn't what it does, but who it does it to, and who it does it for.
