Are we just looking for imaginative ways to destroy ourselves at this point? We have enough options already! But we have to keep looking for more creative previously unknown ways to kill ourselves.
We’ve got to leave something interesting for the alien xeno-archaeologists of the future to uncover.
Xeno-archaeologist 1,000 years from now: … yeah … it’s another one … fourth one in this sector … just blew themselves up and destroyed everything for some dumb reason … probably economics like in that last system 35 light years away … too bad … if we had arrived earlier, we could have helped them out … oh well
Further research shows that they blew everything up trying to deal with the ancient, insatiable, worms they released on themselves out of curiosity. Upon reflection, it is probably better that we didn’t arrive earlier.
