In recent years I've thought quite a bit about the role that technology plays in our world, and I've concluded that the result is an overall negative. Now, before going on, I will admit to owning (computer, car, cell phone, television, air conditioner, etc.) and using as much modern technology as anybody. I am a product of my society. However, the broader point is that I firmly believe that much of the stuff invented since the industrial revolution has put our species on a course for destroying the fabric of our society and eventually our entire ecosystem (though the planet itself will survive us and continue on in some new iteration).
The latest evidence of this is the way that texting has overtaken people's lives -- especially the young. A New York Times article from today talks about some of the social effects of constantly texting, reporting that the average American teen now sends and receives more than 2.000 text messages a month, while for some we're talking 10,000+. They're all going to be unable to use their thumbs in 10 years. I've met 20-somethings at social affairs who could barely look up when introduced to a group and then sat down and texted the rest of the evening. Then, of course, there are those who text and drive -- whether cars or MBTA trolleys.
Technology advances without society pausing to discuss the consequences of the next big thing. Automobiles changed the way we live our lives followed by television and then the Internet. Sure, one can make a case about some of the positives that those items brought to our society -- as have cell phones, microwave ovens, AC, elevators, and on and on -- but the unraveling of the family, the village, the community and the culture that these "advances" have precipitated is disturbing and, I believe, irrevocable.
