Funny, because I was watching the Star Wars cartoon about the Clone Wars the other day, and it was about a clone trooper who started to prematurely execute Order 66 and it was shown that they all had chips in their brains for that purpose. His was damaged and triggered the order early.
Sounds like this stuff is, at best, just a new more high tech form of lobotomy, i.e. destroying or otherwise bypassing neural connections in an effort to alleviate a pathology associated with them.
That's at best. At worst, it's a potential vehicle for mind control. Even if it's not so literal as controlling a person like a video game character, it could still be a form of control by subtly removing emotional inhibitions, etc.
