We have always dovetailed our cognition to our tools, but when our tools start dovetailing back, where do I end and where does the tool begin? It is going to be a really Twilight Zonish situation. It is definitely interesting. Once Google is in a blood cell sized device in our brain, do we become part Google? There are certainly interesting things to think about and provocative questions, but I don't think those provocative questions are going to do anything to slow down the onset of these technologies arriving and becoming even more pervasive.
