Not to mention, did this "hack" ever really work? When the original post went viral showing the Chipotle chatbot reversing a linked list, I (among others who posted their results online) immediately tried it and didn't get the same results, so I always assumed it was just a faked screenshot.
Their chat bot is pretty bad so who knows.
Whether something ever worked is not correlated with traction in a world where verification is measured by likes.
They probably added something to the prompt after that viralness and then it was a cat and mouse game to jailbreak it
