David Chalmers gave a talk today (at the Toward a Science of Consciousness conference in Tucson) arguing that it is fairly likely that sometime in the next few centuries we will create artificial intelligence (perhaps silicon, perhaps biological) considerably more intelligent than ourselves -- and then those intelligent creatures will create even more intelligent successors, and so on, until there exist creatures that are vastly more intelligent than we are. The Splintered Mind

"Within a few decades, machine intelligence will surpass human intelligence, allowing nonbiological intelligence to combine the subtleties of human intelligence with the speed and knowledge sharing ability of machines. The results will include the merger of biological and nonbiological intelligence, downloading the brain and immortal software-based humans -- the next step in evolution." Also found in Are We Spiritual machines? Ray Kurzweil vs the Critics of Strong AI, Gilder and Richards, eds. 1999.

"The human brain is an incredibly impressive information processor, even though it "works" quite a bit slower than an ordinary computer. Many researchers in artificial intelligence look to the organization of the brain as a model for building intelligent machines. Think of a sort of "analogy" between the complex webs of interconnected neurons in a brain and the densely interconnected units making up an artificial neural network (ANN), where each unit--just like a biological neuron--is capable of taking in a number of inputs and producing an output."

"Language, foresight, musical skills and other hallmarks of intelligence are connected through an underlying facility that enhances rapid movements. Creativity may result from a Darwinian contest within the brain." Published in Scientific American 271(4):100-107, October 1994

Subtle refinements in brain architecture, rather than large-scale alterations, make us smarter than other animals. (Scientific American)

Since antiquity, philosophers have argued that higher mental abilities -- in short, thinking and language -- are the great divide separating humans from other species. The lesser creatures, Rene Descartes contended in 1637, are little more than automatons, sleepwalking through life without a mote of self- awareness. The French thinker found it inconceivable that an animal might have the ability to "use words or signs, putting them together as we do." Charles Darwin delivered an unsettling blow to this doctrine a century ago when he asserted that humans were linked by common ancestry to the rest of the animal kingdom. Darwinism raised a series of tantalizing questions for future generations: If other vertebrates are similar to humans in blood and bone, should they not share other characteristics, including intelligence? More specifically, did the earliest humanlike creatures, who split from the ancestors they shared with apes between 5 million and 7 million years ago, already possess a primitive ability to form plans, manipulate symbols, plot mischief and express sentiments?

"Confronted by the discoveries of artificial intelligence, some philosophers are questioning the very minds that keep their profession afloat."

By 2050 robot "brains" based on computers that execute 100 trillion instructions per second will start rivaling human intelligence." Scientific American, December 1999 pp.124-135

Within two to three decades, our brains will have been "reverse-engineered": nanobots will give us full-immersion virtual reality and direct brain connection with the Internet. Soon after, we will vastly expand our intellect as we merge our biological brains with non-biological intelligence.

"Another headline pops up: "Scientists aim to make computer that thinks like a human". And I think no, No, NO! Don't, whatever you do, do that. Even if Ray Kurzweil is the one suggesting it's coming." (Charles Arthur | Technology | guardian.co.uk)
