The Download: Pentagon's AI lie detector and the limits of organ rejuvenation

The latest edition of MIT Technology Review's 'The Download' highlights the Pentagon's $30.3 million initiative to develop 'Polygraph Next,' an AI-powered lie detection system utilizing standoff sensing to monitor physiological responses. While intended to improve accuracy, experts remain skeptical of its efficacy. The newsletter also explores new research on organ transplantation, suggesting that young organs may not provide the 'fountain of youth' some longevity theories propose. Additionally, the publication addresses the failures of the US 'virtual border wall' surveillance program, which failed to prevent over a thousand deaths within its coverage area. Other notable stories include ChatGPT's alleged role in a shooting incident in British Columbia, Ukraine's deployment of military robots via drones, and Google's plans to launch AI-processing chips into orbit. These updates underscore the complex intersection of government policy, emerging biotechnology, and the ethical challenges posed by rapidly advancing surveillance and AI technologies.
