james_nicoll has an interesting thread on his livejournal, debating what would be the proper strategy for humanity to adopt if it found itself surrounded by an incredibly advanced and powerful civilization that was to us what we are the chimpanzees. It's entertaining.
Long-time readers might remember James as the author of "There's Something About Titan", a delightful soc.history.what-if thread which took the piss out of In-the-Sea-of-Time timelines.
