Sadly I can't build a better me as I'm not of robotic construction. And I was a being a bit flippant with the world takeover. But as soon as AI reached human level it would quickly go beyond it given the rate these things improve, allowing it to get to to work on improved models. As something along those lines in the real world think the Tesla robots but improved with far better AI.

Actually thinking about it I wouldn't rule out Musk/Tesla going for the world takeover thing;)
