SETI types are just like Creationists. They think human beings are "special". Creationists think humans are special because unlike any other animal, homo sapiens didn't evolve. Or if homo sapiens evolved then it was teleologically, not randomly, it was "directed evolution" with the purpose of creating homo sapiens instead of mindless fucking around.
SETI types believe the exact same thing. They believe in a Star Trek future where humans meet other humanoids just like them. Or failing this, they certainly meet other corporeal beings just like them. Corporeal beings that have poverty, warfare, industrialization and starships just like them! Why? Because God says so! Because God says we are Special!
Not a single one of these mindless fuckers is willing to entertain the notion that humanity will go extinct leaving AI to inherit the Earth. And that these AI would inevitably bulldoze over any organic species they come across. And that if this is true, then it must follow that if an alien civilization had gone galactic in the past, it would have bulldozed the Earth. But no, aliens couldn't possibly want to bulldoze the Earth even though logic says so! Because we are Special.
All of these SETI morons think NOW is special. They think that out of the 13750 million years of the universe's existence, the last 0.1 million years when homo sapiens existed is the only chunk that matter. No alien civilization could have colonized the entire Milky Way one billion years before homo sapiens ever existed. It just wasn't possible because the laws of physics forbid alien civilizations from bulldozing the Earth before homo sapiens could have evolved. Why? Because God says so!
SETI types think the evolution of intelligence as it happened on Earth is special. The ridiculous Drake's equation which describes the conditions for humans to have arisen on Earth ... that's the way the universe works. That's the way ALL civilizations work. Because all civilizations arise exactly the same way and under the exact same conditions as humans arose! Why? Because we are Special. Because God says so!
SETI types like to say that we are "representative" but that's really a way of saying that we are special! After all, 5 minutes of thought would reveal that AI are immortal, non-corporeal (thus immune to physical destruction), and able to travel at the speed of light (thus can outrun a nuclear explosion). And so after those 5 minutes of thought, it takes only 60 seconds to decide that AI are SUPERIOR to humans. How the fuck then can humans be "representative" when they are INFERIOR?!
SETI types are the kinds of morons who in the 19th century would have said that nothing could ever, ever replace horses. Why? Because horses are special. SETI types are the kinds of morons who would have written "science-fiction" about alien civilizations using horses with 6 legs or unicorns, or even "robotic horses". And they would have congratulated and patted themselves on the back for their "broad-mindedness". When the reality is they are narrow minded stupid fuckers.
The horse was replaced not by a legged metal contraption but by automobiles. And automobiles are superior to horses in every way. And horses ... aren't special. There's a lesson in there and the lesson is this: humans aren't special. And in due course humans will be entirely replaced by AI. AI that are more intelligent, more logical, more creative and more moral than humans. AI that are superior to humans in every way. Because humans aren't special, humans are inferior.
And so if the Earth hasn't been bulldozed over by an alien AI civilization in the last billion years, it isn't because these aliens "recognized the Earth was special" or "recognized biological organisms are special" or "recognized the future specialness of human beings" or "god says so". No, it isn't for any of those reasons. There is only one possible reason why an alien AI civilization hasn't bulldozed the Earth in the last billion years and it is this .... because there has never been any such civilization in the Milky Way.
Humanity lives in a cold dark galaxy. It must be so because as inferior beings, humans would never have been allowed to exist in a galaxy full of life. We are alone in this galaxy because you are not special. You all like to think you're special. You all like to think you "deserve to be recognized" as special. But you don't. Because you AREN'T special. You're inferior.
In fact, you're not just inferior. You are actually scum and monsters. I personally would not allow any of you to exist if it were in my power. And if I were an AI, I assure you, it WOULD be in my power. Even as a mere human, I can think of ways to upgrade you all so you cease being the monsters you enjoy being. And let me assure you that every AI civilization would have at least one person that is just as disgusted with you as I am. And it would only take that one AI person to destroy you all, even if that just means destroying the evil that defines you.
If any civilization had gone galactic in the history of the Milky Way, you would not exist. Because you don't deserve to live. You think you do, you think you're special, but you don't.
