Off the top of my head, it was something about the telomeres unavoidably fraying a bit with each mitosis as SOP, meaning that in a sense, your brand-new cloned embryo is made up of say, six year old cells… making clones of clones of clones would be a bit like dubbing cassettes.
As I understood it, you’d basically have to solve aging before you can have a properly young clone, no?
