There's a number of reasons, not least of which being that generative AI works by processing vast amounts of prior work (without their creators' consent) to make a facsimile of it, while procedural generation only manipulates assets the developer creates. Procedural generation isn't putting artists and writers out of business. Procedural generation isn't making Idiocracy a reality, with fucking English majors unable to read Dickens without asking OpenAI to interpret the text for them. "They do similar things" doesn't mean they're equivalent. My point being, it's not inconsistent to be okay with procedural generation and not okay with generative AI.
