Smart AI + Lazy Humans = Feelings of Hollywood sci-fi being right
The smart thing about Google is that their progress is incremental in the sense nobody will realize before it takes over their lives. In a way it already has, but imagine your relationship with Google in 10 years down the line. You will be literally hooked to it and it will know what you are going to do next. I just wish Don't be evil stays ingrained in that AI :)
