Technology is great but I don't like the idea of voice-activated personal assistance devices, thank you, especially ones with an internet connection and which connect to the mothership.
At the same time, it's a given I think that they're going to become ubiquitous.
This xkcd hits the nail on the head. How will society deal with this 'intrusion' into our privacy? Do we get to the point where you go to visit someone and have to politely ask them what devices they have, and to unplug them from the wall? What about smart mobile phones?
