I have a fear of it every once in awhile, but I think a lot of it is unfounded paranoia on my part. There are still a lot of people (not just old people!) who know very little about computers. I'm still surprised by the number of younger people around me who don't have basic computer skills, or afraid of new technology. By simply existing, those people will probably create their own demographic in the future, and they'll be a job for real humans to deal with it. I don't think technology could ever replace human creativity either. Sure, it might be a novelty at first...but people like knowing that something was created by another human being. That's why there are sites for people who sell their arts and crafts. Other people like buying something unique, not something that can be replicated over and over by a machine in a factory.

I'm having a hard time saying exactly what I mean, but here's a video I watched recently. I think it helps, and it made me feel a little better.

Will Robots Make Us More Human?
