Aside from the ethical issues of cloning, it would be very interesting to observe how a Neanderthal reacts to today's technology, which to him would be almost like pure magic.

I can see how the Khoisan have had no difficulty transitioning into today's lifestyle and it's quite captivating. I imagine that suddenly coming into contact with advanced technology would be very strange from a Neanderthal. It would be very much like if anyone of us came into contact with Alien technology. "How does it work? How did it got here? Where did it come from? Who made this?", a thousand questions seem to pop into human mind at once.
