"The Beginning and the End: The Meaning of Life in a Cosmological Perspective" by Clément Vidal. Technically this is just a "PhD thesis preprint" but it's over 350 pages long. A sprawling manuscript in which the author devises a meaning-of-life philosophy based on systems theory, the conquest of the universe by superintelligence, and other ingredients. The discussions of physics and cosmology are unduly dominated by certain "alternative" theories and could have benefited by orthodox criticism, and no doubt much of the rest should be read skeptically too, but overall, this is worth knowing about, if you're into transhuman cosmo-ethics.
Your description makes it sound like it would be mostly a waste of time and it should go on the very bottom of my reading list.
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that exposure to LW ideas makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
