Let me start by issuing the usual statement that technology is neutral and that what matters is how we use it, though I am not sure how easy it is to distinguish the one from the other.
On the positive side:
Technology promises to allow us to do more, own more and live longer and healthier lives. It promises to remove tedious tasks from our lives and give us free time to learn, explore and be more creative. Advances in transportation allow us to travel further and maintain contact with people throughout the world It allows us to explore nature on ever expanding micro and macro levels.
On the negative side:
We are working longer. Throwing in commute time, 10 hour days are fairly common. The wage gap between the rich and everyone else continues to widen. We have become fixated on technology. We may have thousands of friends on Facebook, but we don’t know who our neighbors are. We frequently switch living locations and jobs so there is no longer any sense of community. We are savaging the natural world to the extent that many biologists say that we are in the middle of a mass extinction. The global village is creating a homogenization of cultures to the extent that everywhere is starting to look the same. Languages are disappearing at the rate of one every other week. With computers becoming more human we run the risk of becoming more mechanical, fatter and lazier.
The good news is that, as things stand now, between dwindling fuel supplies and global warming, our lifestyle is unsustainable. If we are lucky, it will continue to be so, forcing us to cut back and reconsider how we want to use all this technology.
