Computers Are Like Eyeglasses

Thad: There is no real difference between computers and any of the other tools that humans have built and integrated into our lives over the course of our long history. Humans have always built tools, and often when a new one is introduced, there is hand a fear that it will change us in some fundamental and bad way. So is a computer, particularly a wearable computer, something that initially scares us, but ultimately won't challenge the core of what it means to be human? I think it actually is qualitatively different.
