This document discusses several emerging technologies that could potentially be weaponized and become weapons of mass destruction (WMDs) between 2010-2075. These include smart dust, smart clothing, smart bacteria, gel computing, conscious botnets, information waves, optical brain computers, and a solar wind deflection gun. The document warns that advances in nanotechnology, biotechnology, information technology and cognitive science could enable new types of extremism, terrorism and pose catastrophic risks if not developed and applied carefully and ethically. Overall the document presents a vision of rapidly advancing future technologies and their potential for both benefit and misuse unless precautions are taken to guide their development responsibly.
