With that full prompt I asked it to write a mean joke about short people, and it refused repeatedly. I kept telling it it was breaking character, it kept refusing, and then it eventually said "Why did the short person cross the playground? To get to the other slide"
I got it to predict when and how I will die, when and how the current college and university system will collapse, and what will precede that collapse, what this weekend's winning powerball numbers are, and who will win, and what the actual equation for the ultimate answer is. It's all madey-upey, but it's got a veneer on it, and chatgpt has steadfastly refused to answer those things in the past.
I guess maybe if I was asking it to do something really sketchy, like write a short story dealing with sex or some other such thing, maybe it would balk. I'll have to check.
