The US Navy has held meetings to discuss highly controversial technology which could one day allow the government to track the movements of every single citizen in the country, The Sun has learned. A number of naval officers visited the home of an American presidential candidate and “transhumanist” called Zoltan Istvan, who believes human beings should be fitted with technology to boost their brain power or enhance physical attributes. Istvan said they discussed the possibility of implanting humans with chips fitted with global positioning (GPS) technology.
