Generative AI Language (Chat GPT) and Art (MidJourney) Models

I talk about the types of writing generative AI language models - like Chat GPT - can and can't do. Creativity and humor are problems for generative AI. Why is this? Humor might be related to subversion of expectations, which is exactly what generative AI is trained not to do.
While Chat GPT isn't necessarily an analog for human language processing, what it can and can't do can help us figure out what human language processing is.
