Sharing is another word Silicon Valley loves.

Especially is what is being "shared" is someone else's resources and not their own.

It is true that many so-called Sharing Economy platforms start as as altruistic and non-commercial ways to share resources: a sofa on which you can sleep for a couple of nights; a car ride; or a drill you can borrow from a neighbour instead of buying it.

But more often than not, they morph into the exact opposite: ruthless commercial entreprises that become huge thanks to network effects and that care very little about the negative externalities they generate.

Airbnb was born when two students decided to offer a place to sleep on inflatable mattresses in their apartment to the participants to a design event in New York. [1]

Sounds nice, right?

But today entire areas of Paris are so choking full of tourists who rent a flat on Airbnb in the search of the perfect "real" Paris experience that it's not Paris anymore! [2]
