Isn't this article just a bit confused? It talks about light as drug (an interesting topic IMHO), but then it veers off into smart networks that keep lights on only where the people are. This doesn't deal with the over-drugging issue at all. In fact, such a network actually allows us to get our drug more easily; if the lights are off where the people aren't, then it costs less to keep the lights on where they are.
