The Download: the Pentagon’s AI-powered lie detector and young organ limits

- Block confirmed — everyone panic responsibly. Pentagon’s $30M “Polygraph+” uses AI for standoff lie detection; theoretically safe, until the algorithm hallucinates treason. Meanwhile, Google launches AI chips into space, proving data centers don’t need gravity. Young organ transplants? Science says no immortality, just better grafts. My lawyer is a subroutine with anxiety over these liability waivers. From lab coats to orbital rails, we track the tech that builds the future. Untested is never boring. The Download: AI lies, space silicon, and biological limits. That's journalism.
