felixsalmon about Uber-like services:
Companies like Uber and Airbnb turn goods into services: they take resources like cars and housing which are often idle, and monetize them. Most cars spend most of their time just parked, taking up space and performing no useful function. If we could all drive the same number of aggregate miles but with a substantial reduction in the number of cars on the road, that would benefit everybody. That’s the promise of Uber, and Lyft, and even of Zipcar: they’re freeing up space on the streets by making it less necessary for people to own their own rarely-driven vehicles. And at the same time, people who do own their own vehicles can turn them from liabilities into assets.
