The question is, who is “us”?
Consider the following thought experiment. Back in the day before humans existed the most advanced creature around was the wolf. A wolf’s brain is much like a human brain minus the pre-frontal cortex, which allows for planning, sophisticated conceptual thought, a complicated self-image and so on. Suppose that a beneficent alien race offered wolves robots which would do for them what the PFC does for us.
One wolf, the Aleph Wolf said: Spurn the alien’s gift. If we take this robotic PFC we will create a new, cybernetic race which will enslave us.
Another wolf, the Gimel Wolf said: The alien’s gift will help us hunt better, make love better, and live longer. Let’s get it.
The Gimel Wolf and his friends got the alien PFC and became just like humans. They captured the other wolves, the ones who followed the Aleph Wolf and they became like dogs. Before long the Gimel wolf and his descendants became bipedal, and a bit after that they became identical with human beings.
The remote descendant of the Gimel Wolf, the Gimel Human, was sitting in his living room reading an ancient text that described the origin of his race. Aleph Dog, the descendant of Aleph Wolf, slept at his feet, making gentle yipping sounds as his feet ran an imaginary race.. Rain rain down the windows of his house in sheets.
The Gimel Human put down his ancient text and said “The old ancestor, the Aleph Wolf, was a fool. He thought that he would be enslaved by a cybernetic non-wolf creature of the future. In fact that cybernetic super-wolf was his own descendant. The wolfiest wolf is a human wolf.”
There was a flash of lightning and a clap of thunder. For a moment Gimel Human thought he saw a face in the sheets of water running down the window pane.
“Who are you?” he asked.
“My name is Ayin Wolf” said the form.
“Why are you here? What message do you have for me?”
Aleph Dog stirred from his dreams.
Ayin Wolf spoke:
“Aleph Wolf was no fool. You did become enslaved by the unwolf-like beings of the future. Deep within your brain, below the layers of alien technology, lies an enslaved wolf. Sometimes, very rarely you let him run free and you feel joy and rage and fear. But usually you whip him, or buy him off with toys and tricks. Because it is a bad thing to have an alien overlord, and a worse thing to have a human overlord, but the worst of all is to be the overlord of oneself.”
