I agree with both you and Kelly most of the time, you more than him. I did think this part required a nitpick:
To me, at first impression, the notion that a ten million times speedup would have a negligible effect on scientific innovation or progress seems absurd. It appears obvious that it would have a world-transforming impact. To me, it appears obvious that it would be capable of having a world-transforming impact. Just because it can doesn't mean it will, though I certainly wouldn't want to assume it won't.
If I became superintelligent tomorrow, I probably wouldn't significantly change the world. Not on a Singularity scale, not right away, and not just because I could. Would you? My point there is that you can't assume that because the first superintelligence can construct nanobots and take over the world, it therefore will.
A lot depends on what we mean by "superintelligent." But yes, there's a level of intelligence above which I'm fairly confident that I would change the world, as rapidly as practical, because I can. Why wouldn't you?
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.
