we'll develop something that can either rejuvenate us, [...] or cloning.
I never understood how cloning could make someone live longer. If you can't transfer your soul/conscience into the clone, it's not going to get you anywhere.
Just like in the movie The Island, where a powerful insurance company has clones of all its customers. Those clones stand ready to provide for potential failing organs in the body of their real-life counterparts.
Immoral as a concept. Excellent as a sci-fi movie scenario.
