Robert Downey Jr. pledges to use robotics and AI to clean the Earth

Hollywood legend Robert Downey Jr. is putting down his Iron Man suit and taking up the bigger challenge of cleaning up the Earth. Iron Man's on-screen nemesis Thanos had a radical way of reducing humanity's impact on the Earth, but Downey Jr. hopes to use a more humane solution. Appearing on-stage at Amazon's new re:MARS (Machine Learning, Automation, Robotics and Space) conference in Las Vegas, Downey Jr. launched an initiative called Footprint Coalition. "I don't pretend to understand the complexities we face as a species, just because I portrayed a genius in my professional life. My scholastic achievement peaked at a correctional finishing," Downey Jr. joked, in reference to being incarcerated on drug charges and never making it past high school.
