Most of us are, I think, temperamentally opposed to the idea of a society in which we are surveilled 24/7. We look at the proliferation of Ring doorbells, the thickets of CCTV cameras that capture our every trip to the shop from multiple angles, the algorithmic harvesting of our data by every website we use to shop, to exchange messages with friends, or to scour the wisdom of the internet for information, and we give a slight shudder of revulsion.
