Voice Activated Interfaces

Just last week Amazon announced their idea for "Echo", a $199 speaker.  However, it is not just any ordinary speaker, it has a voice control feature that will be able to voices from all the way across the room just by saying the keyword "Alexa".  Not only will it play you music if you ask the sparker too, but it can all answer any random questions you have, much like Siri.  Amazon already began buying smaller companies that will assist them in creating "Echo" in hopes of successfully pulling it off. Voice activated interfaces seems to be an upward trend and in the near future, many predict, you will be able to voice activate so many house hold things such as TVs and security systems.  Does this seem overwhelming?
