Yes, that's basically my concern. I'm aware of the value of tissue preservation for other, "conventional" fields of medicine and science, but developing perfect preservation is just the first step in actually extending human lives. The second step - reanimation or emulation - strikes me as far more controversial and far more difficult as well. I understand the argument that we can postpone this step indefinitely once we've got preservation figured out, but, as I was saying, most people tend to think of their current bodies when they think "life extension".
For those who are interested in this topic, I'm just wondering what longevity research today looks most promising to you and why. Whether that's SENS, cryonics, nanotech, brain uploading, etc is fine with me. Any links to actual research papers would also be greatly appreciated. I'm very interested in longevity, and am curious to see if anyone else would like to offer some thoughts on the current state of the art.
