The world is a really, really complicated contraption, replete with moving parts that can malfunction at any time. You can make a pretty good case that the United States President, along with his science and technology advisers, is in a position of trust, responsible in part for keeping that contraption going. That’s why I support this week’s call for a debate among presidential candidates on technology and science issues. The open letter to the candidates has been signed by Lawrence Krauss of Case Western Reserve, Steven Pinker of Harvard, and other notables. I don’t begrudge the candidates their sniping at one another over minor points of religious doctrine, as for instance, the Romney-Huckabee flap about Satan’s paternity (link via Wired). But people, please, let’s have a forum for the issues that affect our children, our grandchildren, our great-grandchildren, living right here on earth.
