I think my favorite thing about humans are space orcs-style musings is that while the thought exercise is ostensibly about humans being unique in relationship to aliens, in practice it is mostly just an excuse to celebrate the things that we appreciate about ourselves as a species and the world in which we live.
Like yes, you could make a valid argument that "death worlds" are probably common or that other species are also batshit and it's honestly pretty likely that we would consider truly alien environments to be as mindblowing as we imagine ourselves being to other species.
But most of the time when I see people posting in the HASO tag, it's just something cool they noticed about themselves or the people they love and celebrating the joy they feel in being human.
Because really? We don't know what aliens will be like. We have no idea. They could look like anything. But we know that humans poison ourselves for fun, risk our lives to save deadly creatures, pack bond like nobody's business. We're the best endurance runners in the as-yet-known universe. Our brains are so coded for tool use they treat cars and planes and cranes as extensions of our bodies; and so coded for social bonds that we see faces in rocks and trees and teach our robots to sing themselves happy birthday.
And our planet? It has so many kinds of spiders and so many kinds of fungi and so many creatures that like to get pets and SO many animals that will get themselves drunk on fermented fruit or jellyfish zaps if given the chance. Dihydrogen monoxide, the universal solvent capable of dissolving more substances than any other liquid we know, falls from the sky and we dance in it. Our world is deadly as fuck and beautiful in its danger and in its wonder.
At our best, we imagine a future in which we are a benefit and a joy not only to our planet but to the universe. We dream of meeting alien species and inviting them home to meet our parents. We make art imagining all the ways we could be part of a galactic community.
It is sometimes not easy to be proud of being human or to take joy in the world we live in. But then you imagine someone taping a knife to a Roomba and you remember that sometimes, actually, humans can be kind of awesome and it is a privilege to live on this planet Earth.
