I was watching a commercial today on MSNBC for a knee replacement technology. The ad had some woman who lives in San Francisco and the infinitely large hills there were just killing her knees because she had arthritis. But then modern medical science gave her: “a replacement knee that, unlike the ones produced by other companies, bends and turns to ALMOST simulate the function of a real knee.” And it continued with the usual disclaimers - don’t elect to have this done if you’re sick, the knee may gain setience and kill you - stuff like that. But what stuck out for me in the ad was the fact that the replacement knee ALMOST was like a real knee. ALMOST. Are you telling me that modern science can put a man on the moon, build a space station, make computers that store so much information that if you would have told the original creators of the computer you would have been thrown in a luny bin, can manipulate NANO objects to build things for them, yet it cannot make a fully functional knee?!? WTF is that?
