It's an idea, you didn't have to rape it. Of course there are many technical aspects that make the SYG units far superior and much further down the line from a robotic mouse.

The fact that the human brain is very complex doesn't stop us from reading and interpreting certain known signals, then calibrating these signals to a certain action.

Case in point:

Whether a device such as SYGs could exist solely on calibrating signals rather than understanding the basic functions of areas of the brain is yet to be seen. Either way, the SYG units are far from production, but I'm confident that sometime in the far future, such devices will exist(I would guess with a sensor or "brain-jack-matrix-style" rather than a brain being physically removed from the body and put into a computer. If that's still in your lifetime, then you can feel like as ass for raping SYG's idea.
