If people buy and use this, I imagine a future version will work hard to detect if your questions are being directed at it without you having to prefix the request with a keyword like "Alexa".
E.g. If you ask a question and it doesn't hear anybody else respond within a certain amount of time. Or it could use additional sensors to detect if you're alone when you say something out loud, and whether or not you're shouting to somebody else in another room. It wont be perfect obviously and will sometimes look stuff up when it wasn't supposed to.
