Perceptually we filter out the old and constant (or slowly changing) and are captivated by the sudden and new. That was a good thing when nature could just leap out at you and slash your throat, but maybe it's a bit of atavistic baggage when trying to function in civilization, how ever imperfect it is. (Other burdensome instincts: gorging on sugar and fat whenever you find it, trying to spread your genetic material to as many others as possible, violence 'n' stuff.)
On the other hand, time seems to be on the neophiles' side. At least right now, the rate of change seems to increase. I was just reading a children's book (dating from the early 70s) to S0 where a character got a plaster cast after breaking a bone, but I don't think I've seen anybody with that kind of cast in years. And it's not like it's ancient technology either. While technology that lives off network effects like the internal combustion engine or old computer operating systems doesn't fade away very quickly, some new things quickly conquer the old: cell phones are decimating pay phones now, for example. And I admit it: I can't wait to see what happens next.
