Sure OK, maybe it's a beneficial side effect then. However you look at it, trying to get the computer to decide when you are addressing it, without using a name of some sort, could be a very challenging problem to solve, one that even humans struggle with. Surely you've been in a situation where you say something to a room and multiple people think you're talking to them? To borrow an example from elsewhere in the thread, if you say "turn on the lights", are you talking to the computer controlling the room lights, or the human standing next to the Christmas tree?

Could you elaborate on that? What if that were true?
