Obviously it's for entertainment, but there are many channels where content creators post questions that have asked LLMs [1]
I also think many people are prompting image generators to see what they produce. I can remember a time when many images that involved asking ChatGPT to make someone aggressive would make the people in the image black, whereas using neutral terms would have them generate as white.
I also remember asking early GPT 4 LLMs to explain something to me like a 5 year old from X location and basically seeing the network produce varied responses as it was clear it had an idea of some 5 year olds from one city being inherently smarter than others. Then you can change it to say a 5 year old girl or a 5 year old boy and it would dumb things down a lot more for the boy.
