Greater strength and endurance. Enhanced thinking. Better teamwork. New classes of genetic weaponry, able to subvert DNA. Not long from now, the technology could exist to routinely enhance — and undermine — people's minds and bodies using a wide range of chemical, neurological, genetic and behavioral techniques.
It's warfare waged at the evolutionary level. And it's coming sooner than many people think. According to the futurists at the U.S. National Intelligence Council, by 2030, "neuro-enhancements could provide superior memory recall or speed of thought. Brain-machine interfaces could provide 'superhuman' abilities, enhancing strength and speed, as well as providing functions not previously available."
Qualities that today must be honed by years of training and education could be installed in a relative instant by, say, an injection or a targeted burst of electricity to the brain. Rapid advancements in neurology, pharmacology and genetics could soon make such installations fairly easy.
