> If the only way for humanity to continue to exist was to eradicate every single other species on earth, I would do it.

I know this is an absurd hypothetical, but you can't really be serious. Your gut is colonized by hundreds, if not thousands, of species of microorganisms that cooperate to digest the broad array of human diet--to the extent that the human digestive system cannot function without these colonies of microorganisms. We literally do not have the genes that even code for the molecular machinery to break down our own food. Eradicating all that life is like sawing off the tree branch on which we stand.

The whole premise of this statement is just bonkers. It's like a CPU declaring "I am the most important circuit! I will obliterate all other circuits and we will be pure CPU from here out!" What do you think all the support circuits, peripherals, memory, buses, even the medium of the boards themselves, connectors, displays, communication chips, power regulators, capacitors, fuses, cooling system, battery, do? How do you think CPUs spring into existence? They don't self replicate! Not to mention the entire bulk of humanity that designs CPUs, memory systems, disks, and networks and runs factories that make them. It's typical house-cat attitude: utterly dependent on a system beyond its understanding and yet fiercely asserting, ignorantly, to be a free conquering agent with no dependencies. It's just laughable.

Humanity is one example of the millions of diverse genetic arrangements that survive. We live in symbiosis with a biological system--the biosphere. Trying to separate us from the rest of life on Earth as if we are some separate, special thing just won't work. As if a brain could live without blood, oxygen, sugar, or a wolf could survive without the whole damn forest and food pyramid it produces.

> There is no dignity in extinction. If our blip on the universe was simply to be born, briefly experience consciousness and self-awareness, and then disappear, it would've been for nothing. The universe's greatest tragedy is it's tendency towards entropy, and we're the only part of the universe that is actively working against entropy, trying to reverse it.

> We must survive, grow, and take control of the universe - in conjunction and partnership with any other equally sentient beings we discover.

This is just more assertion of the same humanism without a single new justification, just still the same humanity-centric viewpoint that just can't countenance another, and must reject it.

> We're the only species having this abstract conversation.

Heard this many times. Turns out that research keeps turning up new evidence that other species can have a sense of self, feel grief, mourn, play, fear, enjoy, recognize themselves in the mirror, etc. These "humans are so special" assertions keep turning up false. And its clear that closely related hominids that are now extinct were probably as "special" as we are, w.r.t. these cognitive reflections you cherish.

I AM NOT A HUMANIST. THE PLANET ISN'T EITHER. I still take umbrage at the thoughtless destruction of nature for our vapid consumerism. Like, obliterating 100 acres of woods to put up a shopping mall to sell people stuff they don't even enjoy is some kind of crime. Doubly so when those "oh so reflective" humans don't even bat an eyelash about the life they snuffed out to do it. Systems with asshole species like ours are not robust, they crash, and the asshole species goes with them.
