This question sounds familiar with one asked about an old boat. When, during the course of a boat's life, as it is repaired with new parts, does it cease to be the boat it originally was? I thought about it and decided that when its purpose changes the boat would have taken on a new identity.
Comment on Re: At what point is the coding more yours?
I like the axe analogy, along the same lines as the boat: If you break two handles, and put three new heads on it, how can you still call it your trusty old axe?
