Though it is fashionable to say the internet is making us stupid, futurist Jamais Cascio just published an article in The Atlantic refuting that idea. In fact, he thinks computer networks and biotech are an evolutionary response to global crisis.
Cascio's basic premise is this:
Here's an optimistic scenario for you: if the next several decades are as bad as some of us fear they could be, we can respond, and survive, the way our species has done time and again: by getting smarter. But this time, we don't have to rely solely on natural evolutionary processes to boost our intelligence. We can do it ourselves.
Most people don't realize that this process is already under way. In fact, it's happening all around us, across the full spectrum of how we understand intelligence. It's visible in the hive mind of the Internet, in the powerful tools for simulation and visualization that are jump-starting new scientific disciplines, and in the development of drugs that some people (myself included) have discovered let them study harder, focus better, and stay awake longer with full clarity . . . And advances over the next few decades, driven by breakthroughs in genetic engineering and artificial intelligence, will make today's technologies seem primitive . . .
Scientists refer to the 12,000 years or so since the last ice age as the Holocene epoch. It encompasses the rise of human civilization and our co-evolution with tools and technologies that allow us to grapple with our physical environment. But if intelligence augmentation has the kind of impact I expect, we may soon have to start thinking of ourselves as living in an entirely new era. The focus of our technological evolution would be less on how we manage and adapt to our physical world, and more on how we manage and adapt to the immense amount of knowledge we've created. We can call it the Nöocene epoch, from Pierre Teilhard de Chardin's concept of the Nöosphere, a collective consciousness created by the deepening interaction of human minds.
