"My luck they’d clone several copies of me and I’d either have to hunt them down, or they’d come looking for ‘the original’."

Clones won't have your memories. Without memories, they would just be meat-sacks.

So, in addition to learning how to grow tissues of various sorts, blood cells, muscle cells, neurons, and bone, and learning how to knit them together, we'll have to figure out how to program and animate them.

Now here's a thought; what happens if your memories get stuck into someone else's clone?

Let's say you paid to be rejuvenated, and due to a mix-up, you get not only a new healthy and younger body, but one that has a completely different shape and appearance.

Suppose, in your instance, that this new body is female.

I guess you'd be in a conundrum, hum?

Memories are stored in the brain cells via chemical and physical methods.
Nanites of sufficient ‘smarts’ may be able to copy these and reproduce them.

And what you can copy, you can alter, and what you can alter you can similarly ontrol.

Suppose, in your instance, that this new body is female.

Uh, I dunno. Is she hot?

If so, I'd at least have viable options when told to go !@#% myself.

Clone? Memories? “Mr. Murder” comes to mind. Scary stuff.
