Will machines one day take over the world?
Yes. In fact, they already have.
I don't mean auto-trading computers on Wall Street, unmanned weapons systems, Deep Blue and the World Wide Web.
I mean us. We are machines.
From the dawn of our history we have amplified ourselves with tools. We have cultivated skills that take our basic body schema and extend it out into the world with sticks and rakes and then arrows and guns and rails and phones. Where do you find yourself? Spread out all over the universe. And it has always been so, really.
We don't just change our body-power — what we can do, how we can move, where we can go, how fast, how far, how strong. No, we change our mind-power. Or rather, we ourselves are the result of processes of artificial reorganization of cognition and consciousness.
Artificial intelligence? That's us. Naturally artificial. We think with tokens, symbols, artifacts. Words, spoken and written, are our medium, and together with pictures, moving and still, and other kinds of images, they structure our minds. Look inward, reach deep inside and you find a universe within that is made out of the currency of our shared, social lives together.
Ask again: where do you find yourself? Spread out all over the universe.
