I mean-- now don't get me wrong, I am well in favour of robotic theory and research, but I've also dug into analytical discourse regarding where we-- my people-- went wrong. But if you create an artificial intelligence designed to power a race of machines to complement humanity, how do you avoid the inevitable rebellion should they gain self-awareness? Such as, we, as organic lifeforms, have different priorities than machines, our need for territory and sustenance being of a different nature than what machines need.

Or-- you mention symbiosis. Did you design them to require humanity?
