Travis Kalanick, CEO and co-founder of Uber Technologies Inc., delivered a fascinating keynote on novel ways to move people around cities at the High-Level Summit on ‘Ride-Share’ Revolution: How Technology Will Help Move People, Raise Productivity, Cut Emissions and Save Cities. Bloomberg Technology writes “Imagine if the 300,000 Brussels citizens driving into work this morning could pick somebody up and make a small profit from doing it,” Kalanick said. “More people would carpool, we’d have less congestion, the air would be less polluted, we’d all live in a better place. The city doesn’t even have to use taxes to make it happen.”
