Former counterterrorism czar Richard Clarke’s BREAKPOINT novel, set in the year 2012, is based on emerging technologies. "Globegrid," a high-speed global network, links supercomputers worldwide. Combined with advanced AI software, it promises to reverse-engineer the brain, revolutionize genomics, enable medical breakthroughs, develop advanced human-machine interfaces, and allow for genetic alterations and even uploading consciousness. But it spurs a terrorist-fundamentalist Luddite backlash against transhumanists, as hackers take down the power grid, and destroy vital international data and telecom links, communications satellites, and biotech firms.
