Evolution is not an inevitable march forward into perfection; it is an unending, unyielding, messy red. Like death, he visits us all. Like death, he is not cruel.
The current iteration of our world, our bodies, ourselves is the best it will ever be! The great bias of history.
We forget we are the next in the line of progression to be bumped off eventually and maybe we are the failed branch in the family tree. It is not for us to know. It will be those digging up the impressions of our bones on rock our names and dreams forgotten who decide.
