Generative AI sabotages the proof-of-work function by introducing a category of texts that take more effort to read than they did to write. This dynamic creates an imbalance that’s common to bad etiquette: It asks other people to work harder so one person can work — or think, or care — less. My friend who tutors high-school students sends weekly progress updates to their parents; one parent replied with a 3,000-word email that included section headings, bolded his son’s name each time it appeared, and otherwise bore the hallmarks of ChatGPT. It almost certainly took seconds to generate but minutes to read. As breaches of etiquette go, where this asymmetric email falls is hard to say; I would put it somewhere between telling a pointless story about your childhood and using your phone’s speaker on an airplane. The message it sent, though, was clear: My friend’s client wanted the relational benefits of a substantial reply but didn’t care enough to write one himself.
