Funny thing, I was having such a conversation with colleagues last night...remembering the vast technological transformations that have occurred in just a few decades.
We were sitting in a bar and grille looking at all of the flat panel plasma TVs and telling stories about seeing a color TV for the first time!
I think its ironic that I have a career doing something that didn't even exist when I was a kid!
But I agree with the previous posts...all this technology allows us to do more with less time, and now we are too busy to engage in the social activities that were necessary to survive in the pre-industrial era...
