It\u2019s 2022 and you\u2019ve just arrived at the travel destination of your dreams. As you get off the plane, a robot greets you with a red laser beam that remotely takes your temperature. You\u2019re still half asleep after a long transoceanic flight, so your brain barely registers the robot\u2019s complacent beep. You had just passed similar checks when boarding the plane hours ago so you have nothing to worry about and can just stroll to the next health checkpoint.<\/p>\n
