Uma matéria foda do NYT sobre Singularity e Ray Kurzweil:

“We will transcend all of the limitations of our biology … That is what it means to be human — to extend who we are.”

E um post foda do BBH Labs sobre esta matéria, com uma citação foda do Chris Anderson:

“This was one of those freaky moments when the future sneaks up and smacks you….Technology wants to be invented and we are almost powerless to stop it. We are hard-wired to create the future, be it good or bad. Invention is its own master.”

Complementando o post aí de baixo, mais uma idéia fascinante e assustadora, desta vez do futurista Ray Kurzweil. Trata-se de uma simulação a partir da nanotecnologia:

In his book, The Singularity is Near, futurist Ray Kurzweil describes how a nanotechnology powered neural network could give rise to the ultimate virtual reality experience. By suffusing the brain with specialized nanobots, he speculates that we will someday be able to override reality and replace it with an experience that’s completely fabricated. And all without the use of a single brain jack.

Here’s how:

First, we have to remember that all sensory data we experience is converted into electrical signals that the brain can process. The brain does a very good job of this, and we in turn experience these inputs as subjective awareness (namely through consciousness and feelings of qualia); our perception of reality is therefore nothing more than the brain’s interpretation of incoming sensory information.

Now imagine that you could stop this sensory data at the conversion point and replace it with something else.

That’s where the nano neural net comes in. According to Kurzweil, nanbots would park themselves near every interneuronal connection coming in from our senses (sight, hearing, touch, balance, etc.). They would then work to 1) halt the incoming sensory signals (not difficult—we already know how to use “neuron transistors” that can detect and suppress neuronal firing) and 2) replace these inputs with the signals required to support a believable virtual reality environment (a bit more challenging).

As Kurzweil notes, “The brain does not experience the body directly.” As far as the conscious self is concerned, the sensory data would completely override the feelings generated by the real environment. The brain would experience the synthetic signals just as it would the real ones.

Em me sinto um primata pensando assim, mas esse futuro aí em baixo deve ser uma merda, apesar do texto – assinado por Nick Boltrom, professor de Oxford – ser do caralho.

Intelligence is a big deal. Humanity owes its dominant position on Earth not to any special strength of our muscles, nor any unusual sharpness of our teeth, but to the unique ingenuity of our brains. It is our brains that are responsible for the complex social organization and the accumulation of technical, economic and scientific advances that, for better and worse, undergird modern civilization.

All our technological inventions, philosophical ideas and scientific theories have gone through the birth canal of the human intellect. Arguably, human brain power is the chief limiting factor in the development of human civilization.

Unlike the speed of light or the mass of the electron, human brain power is not an eternally fixed constant. Brains can be enhanced. And, in principle, machines can be made to process information as efficiently as—or more efficiently than—biological nervous systems.

There are multiple paths to greater intelligence. By “intelligence,” I here refer to the panoply of cognitive capacities, including not just book smarts but also creativity, social intuition, wisdom and so on.

There are traditional means of enhancing intelligence, like education, and newer means like biotechnology. Perhaps the smartest and wisest thing the human species could do would be to work on making itself smarter and wiser. In the longer run, however, biological human brains might cease to be the predominant nexus of earthly intelligence.
