Man After Man: An Anthropology of the Future/YMMV


 * Nightmare Fuel: Dear Lord..so..so much. Mainly in the books' highly detailed illustrations of evolved and genetically altered human/animal species. One notable species is called the Tic; a human with an organic version of the cybernetic cradle the Hiteks get around in. They're completely dessicated humanoids whose organs are constantly failing, so they replaced them with artificially grown organs. It was simply more convenient to grow entire organic exoskeletons. They are not a separate species from the Hitek, their technology is simply more advanced.? In addition, many of the creatures appear as if someone needs to call in Master Chief and have the whole planet nuked from orbit.
 * Uncanny Valley : So much it hurts.
 * Unfortunate Implications: It's not that difficult to read a lot of the early sections (especially those dealing with the Hitek and Tek) as an Author Tract advocating eugenics.
