Unnatural Selection is the first book to examine the rise of the "technocentric being" - or geek - who personifies a distinct new phase in human evolution. People considered geeks often have behavioral or genetic traits that were previously considered detrimental. But the new environment of the Anthropocene period - the Age of Man - has created a kind of digital greenhouse that actually favors their traits, enabling many non-neurotypical people to bloom. They resonate with the technological Zeitgeist in a way that turns their weaknesses into strengths. Think of Mark Zuckerberg versus the towering, Olympics-bound Winklevoss twins in the movie Social Network.

Roeder suggests that the rise of the geek is not so much the product of Darwinian "natural selection" as of man-made - or unnatural - selection. He explains why geeks have become so phenomenally successful in such a short time and why the process will further accelerate, driven by breakthroughs in genetic engineering, neuropharmacology, and artificial intelligence. His book offers a fascinating synthesis of the latest trends in these fields and predicts a 21st century "cognitive arms race" in which new technology will enable everyone to become more intelligent and "geek-like".
