As an illustration of how [the hope for radical human enhancement is fraught with](https://www.lesswrong.com/posts/EQkELCGiGQwvrrp3L/growing-up-is-hard) technical difficulties, ["Changing Emotions"](https://www.lesswrong.com/posts/QZs4vkC7cbyjL9XA9/changing-emotions) sketches a picture of just how difficult an actual male-to-female sex change would be.
It would be hard to overstate how much of an impact this post had on me. I've previously linked it on this blog eight times. In June 2008, half a year before it was published, I encountered the [2004 mailing list post](http://lists.extropy.org/pipermail/extropy-chat/2004-September/008924.html) that was its predecessor. (The fact that I was trawling through old mailing list archives searching for content by the Great Teacher that I hadn't already read, tells you something about what a fanboy I am.) I immediately wrote to a friend: "[...] I cannot adequately talk about my feelings. Am I shocked, liberated, relieved, scared, angry, amused?"
