I am not sure if I would pay for ChatGPT. Yesterday I had it get stuck in a loop giving me the same piece of text over and over But I would probably accept a fixed and low monthly fee. Actually the Wikipedia API and a summary API could cover some of my needs. I think that Markov chain models or whatever they were called could do decent text generation. Not as good as GPT of course, but that technology is much simpler to implement. I won't be surprised if someone uses it in a novel way soon.
