Who knows if people will get to try it twice. Such a thing might take over the first time and be able to sustain its power indefinitely (until human extinction)

Who knows if people will get to try it twice. Such a thing might take over the first time and be able to sustain its power indefinitely (until human extinction). I have a lot of hope though that it won't be tried. "It would just fail" is a bad argument against trying it because it sounds like you get another chance to do something else after.
