Friction is an important property in any system. It’s neither a good nor a bad thing out of context. Low friction is valued in the context of a car’s energy efficiency for example, and high friction is valued in bringing the exact same car to a safe stop. If Alice faces a choice between less or more friction in a digital system, between more or less convenience, you know the choice Alice is going to make. Should Alice opting for lower friction / higher convenience correspond to what’s best fo...
