Probably scared by the fact that the title said "Brain chip reads man's thoughts" when that really isn't what's happening. It's simply locating areas in the brain which are active when certain activities are done and inserting electrodes on those areas in order to activate machinary or software designed to emulate said action.
We already have them. They are called "missles".
You do need to trigger a missile. Once it's in flight you don't really have to worry about it. Off hand I can't think of any missiles that don't need human intervention to fire. Most involve a trigger of some sort.
