Art becomes life.. in "The Circle" a randomer gets chased down and accidentally killed as a "product demo", and in Westworld series 3, Caleb gets assigned vigilante tasks via the RICO app.
Imagine you just got hit by a car. You are lying on the ground. You see a stranger pull up their phone. Are they calling 911 for you? No, they are there to record you being hauled off in a stretcher on perhaps the worst day of your life to be the first to post it online. The Black Mirror writers must have invented this app.
