Very overblown. The trick with the color-changing lamp is more of a hack than a true BCI. It's reading your brain, but not something occuring in your conscious thoughts. If it's implemented like I think it is, there's an observable signal in the brain from looking at a high frequency oscillating light source. What's not happening is an analysis of signals to recognize you're consciously thinking about green or holding the concept "green" in your mind.
