Since the 60s we've imagined the combination of computers and our environment would create both utopias and dystopias. Since the 80's we've seen academics, artists and corporate R&D labs prototype these futures from the top-down. Now, hackers are building sensors, bots and software into everything around them bottom-up, fast, cheap and out-of-control. They're creating environments that react, adapt and respond to us - and perhaps more importantly - each other: The Demon-Haunted World. Matt's session will be a whistlestop tour of those days of future past and pointers to some practical futures we can start building right now, together."
