and um but a bit of you know eventually and if nothing if none of that happens and somehow magically we keep going then the sun will the sun is gradually expanding um and will engulf the earth um and probably earth gets too hot for uh life in uh about NUMBER_TOKEN million years it's a long time but that's only NUMBER_TOKEN longer than earth has been around and so if you think about like the because the current situation is really remarkable um and kind of hard to believe but uh it's been around four and a half billion years and this is the first time if one half billion years that has been possible to extend life beyond earth and that window opportunity may be open for a long time and i hope it is but it also may be open for a short time and we should uh i think it was wise for us to uh act quickly while the window is open just in case it closes yeah the existence of nuclear weapons pandemics all kinds of threats yeah should uh should kind of um give us some motivation i mean civilization could get um could die with a bang or a whimper you know if it's uh if it dies a demographic collapse then it's more of a whimper obviously but if it's world war three it's more of a bang but but these are all risks um i mean it's important to think of these things and just you know think of things as like probabilities not certainties um there's a certain probability that something bad will happen on earth like i think most likely the future will be good um but there's like let's say for argument's sake um a one percent chance per century of of a civilization ending event like that was stephen hawking's estimate um i think he's he might be right about that uh so then uh you know we should basically think of this like being a multi-planet species just like taking out insurance for life itself like life insurance for life
