Charlie Brooker wonders about the obsessive default auto-sharing of apps like Spotify in the The Guardian:
If the Walkman had, by default, silently contacted your friends and told them what you were listening to, not only would no one have bought a Walkman in the first place, its designers would have been viewed with the utmost suspicion.
You know how annoying it is when you’re sitting on the train with a magazine and the person sitting beside you starts reading over your shoulder? Welcome to every single moment of your future. Might as well get used to it. It’s an experience we’ll all be sharing.
