Take off that tin-foil hat! You seriously think the next logical step for this kind of tech is human slavery?
Wouldn't robotics be a better option for creating autonomous drones than taking over human brains? Also, wouldn't that create a lot less outrage? Seems like a simple choice:
* Spend 250,000 man-hours designing autonomous machines that can do repetitive tasks for us, bringing with it the pride of technological achievement.
* Spend 1,000,000+ man-hours hacking the human brain so that we can hijack people for slavery, bringing with it the shame of moral/ethical condemnation.
You really think that people in power are going to chose the more expensive, less ethical option?
This is much more of an exercise in understanding primitive brain structures. The fact that we have actually accomplished one of the fantasy-technologies from "The Fifth Element" is pretty incredible, actually. We have learned a lot about how biological neural networks work, and this is what we have to show for it.
And yes, it is "just a cockroach". Wait till you find out what we have been doing to monkeys for the past 50+ years!
