That is so many generations. Imagine you are just the 4. architect. Your great grandfather has started it, but you did not know this man. Somehow the plans have been passed down to you, but of course there were changes... Somebody after you is going to finish it. You do not know how it's going to look in the end, because there will be more changes later. If they will be able to finish it at all....
Must be kinda frustrating to be the second generation or something. You didn't start it, and you'll never see it to be finished, not even close. You're just kinda there.
