I'm not sure that refactoring our genome is going to be enough. We need bodies that can survive cosmic radiation as well as maintain structural integrity for the thousands of years required for most interstellar trips. We probably also need a psychology that doesn't recoil in horror at the thought of 10,000 years in space. And frankly, we probably aren't smart enough to do space travel well, even if we did have radiation-hardened bodies with million-year lifespans. Even saying "we need a rewrite" doesn't cover it, as that still implies the same design goals. We need to rethink ourselves from first principles to have any chance. To draw upon the IRS example from the article, this isn't a matter of slapping a web front-end on software from the 60s. This is more like trying to adapt 50 year-old tax return software commissioned by the US government, to run the server for your new MMO (and, I suppose, reworking that web front-end to act as the client, heh). There is not a single thing about the human body adapted to space travel including our brains - why would there be?
