According to Mark Roeder the rise of the geek represents a new phase of human evolution. In his book, Unnatural Selection: Why The Geeks Will Inherit The Earth[15] he suggests that "the high-tech environment of the Anthropocene favours people with geek-like traits, many of whom are on the autism spectrum, ADHD, or dyslexia. Previously, such people may have been at a disadvantage, but now their unique cognitive traits enable some of them to resonate with the new technological zeitgeist and become very successful."
