Thanks. I address immortality early on because it is a main point that Kelly addresses throughout his short piece. I appreciate your point about meta-research, but my intuition says that it might be even harder for many to grasp than the points in the post. Can you name concrete instances where meta-research led to breakthroughs?
I wrote a blog post responding to Kevin Kelly that I'm fairly happy about. It summarizes some of the reasons why I figure that superintelligence is likely to be a fairly big deal. If you read it, please post your comments here.
