This book was a complete surprise. Written in 1952, Simak's view of the evolution of humanity and what is left behind seems very prescient. His references to AI and virtual reality, the downloading of minds into other creatures, all seem achievable within another generation. His use of robots as the steady overseer of man's creation, and ultimately a creator in its own right, hit me squarely in my SF-lover's core. Highly recommend.
