At least the AI generated posters are better than human-generated t-shirt designs, where you find generic texts such as: "Est. 1984" (or any random year), "I [heart] NY", "Property of [City/School] Athletic Dept.", "Original Trademark", "Authentic Denim Brand", etc., etc.
I don't often say this but those jobs are ripe for replacement by AI. It won't do worse!
