This is one of the questions I get asked most often since I started to cover the topic of asteroid impacts. Will humans will become extinct within a decade, or within a century?

Technology advances so rapidly that you can't look much further than that, as you can see by predictions of the present from thirty or more years ago. It would be nice to look further ahead, but what may seem major issues for the future now may never happen and other things that we haven't even thought of might be the big issues of the day in the 2040s.
