I got Moravec's latest book, "Robot: Mere Machines to Transcendent Mind", out of the Library when I was there looking for Kauffman's "Investigations". Even if you're not interested in Robots you should read this book. The key is "... Transcedent Mind". Moravec does not think small. He is as interested in the Singularity as the next
Extropian, it is just that he thinks of everything in terms of robots.
But by chapter 6, "The Age of Mind" he starts with a subsection called "Robots' End" which begins like this:
    "Exes will put astronomically more thought into their actions than Earth's small-minded biological natives can muster. Yet, viewed from a distance, Ex expansion into the cosmos will be a vigorous physical affair, a wavefront that forges inanimate matter into machinery for further expansion. But it will leave a subtler world, with less action and even more thought, in its ever-growing wake."
Anyway, Moravec is one of those, along with Kurzweil, that belives that mind is more powerful than physics. If you haven't yet plowed all the way to the end of Kurzweil's precis[1], I recommend that you make the time. It is very heady stuff.
