Instead of "vending machine", I see many people calling generative AI "slot machine", which more aptly describes current genAI tools.

Yes, we can use it 10,000 times to refine our recipes, but "did we learn from it"? I am doubtful about that, given that even after running with the same prompt 10 times, it will give different answers in 8/10 responses.

But I am very confident that I can learn by iterating and printing designs on a 3D printer.
