Good read. But if there is a conclusion to be drawn here, it's that we have a severe lack of common-sense POVs about human enhancement. On one end we have Ray Kurzweil, and on the other we have articles like this. The real useful path is provigil-like incremental steps, which are utterly marginalized and looked upon with suspicion. And this kind of small steps can be seen quite often in the past few years... from a flash game that increases IQ to electrodes that greatly enhance memory making to 100 times more cognitive science articles then 20 years ago.

You don't have to upload to live 120, You just have to get over Alzheimer and cancer and strokes. You don't have to be able to completely understand the brain in order to learn faster or be more productive. There are already many many things we can do, but as far as I can tell we have a problem of perception: making medicine to cure dandruff is commendable, but any kind of enhancement is frown upon. This also is religion at work.
