Or the first two books in the Ware tetralogy, as they now are. I read Software many years ago, and enjoyed it, though not as much as some of Rucker’s others, notably White Light.
This time round it was fine, and so was the second one, but not really anything to write home about. I’ll read the other two, since I’ve got the combined edition on my Kindle, and they’re not very long. But there’s a spark that Rucker has when he writes about things like infinities, that just isn’t there when he writes about the themes here.
Which are artificial intelligence, machine sentience, and the possibility of transferring human consciousnesses into robot bodies and vice versa. Those are fascinating concepts, but the stories don’t quite jump off the page enough for me.
