Sidewalk Labs, the smart city technology firm owned by Google’s parent company Alphabet, released a plan this week to redevelop a piece of Toronto’s eastern waterfront into its vision of an urban utopia — a ‘mini’ metropolis tucked inside a digital infrastructure burrito and bursting with gee-whiz tech-ery. A place where high-tech jobs and affordable housing live in harmony, streets are built for people, not just cars, all the buildings are sustainable and efficient, public spaces are dotted with internet-connected sensors and an outdoor comfort system with giant “raincoats” designed to keep residents warm and dry even in winter.
