I recently saw an AI generated post in r/food.
I ate the ultimate peanut butter cake (Recipe in Comments), and it bothers me that people are already testing the limits of what they can get away with using AI to post. I don't know if this is an attempt to automate the karma accumulation process for bot accounts, or if someone is just testing out AI for the lulz, but I'm not looking forward to trying to moderate Reddit amidst a flood of AI bullshit.
This example wasn't too hard to be sure was AI. The "recipe" didn't include any sort of method, and probably would not have made anything like the image, but that cake does look pretty tasty if you're just scrolling past and not looking too close. As programs continue to advance, I suspect it will become ever more difficult to distinguish between a real post and AI fakery, at least for simple stuff like food photos and recipes.
