Sorry, I didn't read through the article, but just its introduction brought an issue to my mind. Concerning the development of humans, will we strive to eliminate our flaws or to amplify our better qualities? Because in my opinion, having no flaws means that there is no natural direction for the person to go. If you can do anything, why bother?
So if Transhumanism is going for a flawless humanity, thanks, I'll pass, I like being a personality. Being without error is effective, but not very interesting or humane. I think I'll hold on to my "flawed, but perfect" point-of-view for the time being.
Interesting line of thought, though. It's about time someone published that.
