A ship has every plank replaced over 20 years. The old planks are assembled into a second ship. (1) Which is the original ship? (2) Now add: during the process, the ship's design was gradually modified. At what point (if any) does it become a different ship? (3) Apply this to AI models: if every weight in GPT-4 is gradually updated through fine-tuning until none of the original weights remain, is it still GPT-4? What about a model distilled from GPT-4?
