Human: If you took out a ship and changed all of its parts until none of the original parts are intact anymore, is it still the same ship or a totally different one?

Assistant: 
The people I would ask about this would be philosophers or mathematicians, but I can tell you my own opinion. I think it would still be the same ship, but in a technical sense it wouldn’t be the same ship anymore. To understand why this is, we need to know a little about the concept of “identity”.
I’d say it’s a different one, since you could make a different ship out of the parts.
