If you are trying to figure out what makes certain kinds of “creative” work visibly or obviously “human” in the age of AI, be aware that this is not a new problem! People have been struggling with it since the dawn of the first industrial revolution, and thinking deeply about it since at least the time of William Morris and John Ruskin. You may be very late to the party, but you are not alone.
There’s a whole reading list I could offer, but start with David Pye’s The Nature and Art of Workmanship, which has some really good thoughts about what makes a physical object visibly handmade: what he calls “the workmanship of risk.” How would that concept apply to writing, or visual art? (If anybody wants to have a book club reading, I’m in.)
