My friends will often use it for humorous situations that are happening to us in the moment. Overexagerations or putting one of us in a crazy situation.

To me AI art is only about the why. It brings entertainment, comfort, hilarity and agency. I would never charge anybody for it I'm just doing it because I find it a neat set of tools to mess around with. And the tools aren't just asking chatgpt to make something. You can spend months refining the craft of it similar to learning something like Photoshop.
