Reading "A Deepness in the Sky" by Vernor Vinge. It's pretty good, but is a little over excited about the magical power of markets and trade. (He gets a little preachy on this point and it's tiresome, without ever being so wrong that I felt the need to put it down.)
Like Asimov, Vinge seems to subscribe to the notion that a science like psychohistory ought to be possible. He shows us humans thousands of years in the future with choices informed by thousands of years of human history.
