In the show "Foundation" on Apple TV, the emperor of a galactic civilization clones himself to continue as an eternal ruler. He has 3 versions of himself at all times - a young boy, a grown man, and an older version of himself. He has an AI (humanoid) caretaker that raises all of the clones from the moment they are "born" and lives through generations after generation for thousands of years.

I though that was an interesting concept.
