I'm actually reading this now, and understand the point that he's trying to make; it is an excellent argument! I think that I agree with the idea that consciousness will emerge, but there are still other problems that I wonder about, like continuity of identity, which is highly related. Particularly uploading highlights the problem, and Hofstader crosses this ground with Aunt Hilary, the sentient ant colony (I think the joke here assumes the American pronunciation of Aunt as "Ant"). She emerges from the ant colony after the previous sentience is destroyed when the ants become temporarily scattered. Loss of continuous identity.
I would think that libertarians would find continuity of identity paramount, and transhumans like uploading, so there is a crucial problem which we will have to solve in the near future.
