All that it reveals is that our suspicions of ontological nihilism were likely correct all along. The universe does not give you purpose or reason. You make your own.
That is not completely correct. We have inherent biological drives from lower level temperature regulation and such to nutrition intake and on an even higher level a proclivity for social interaction including reproduction. The ways these frames can be aligned and satisfied are not infinite. So some level of constraints and requirements are pre-specified. A person’s chosen behaviour must fit within this structure and that of others for it to be sustainable.
