Tom Chatfield - Cyborg Dreams

Tom Chatfield is the author of How to Thrive in the Digital Age (School of Life), among other books, and he is a regular contributor to Aeon, from where this article comes. Chatfield is a regular commentator on media and technology, and in this piece he questions whether we are using all of our screens or if they are using us.

In essence, the question is whether all of our digital gadgets are an integrated part of our extended minds, or if they are masters of our time and awareness.

Cyborg dreams


Digital gadgets are the first thing we touch in the morning, and the last thing we stroke at night. Are we slaves to their magic?

Today, depending on your favoured futurist prophet, a kind of digital Elysium awaits us all. Over millennia, we have managed to unshackle ourselves from the burdens of time and space — from heat, cold, hunger, thirst, physical distance, mechanical effort — along a trajectory seemingly aimed at abstraction. Humanity’s collective consciousness is to be uploaded into the super-Matrix of the near future — or augmented into cyborg immortality, or out-evolved by self-aware machine minds. Whatever happens, the very meat of our physical being is to be left behind.

Except, of course, so far we remain thorougly embodied. Flesh and blood. There is just us, slumped in our chairs, at our desks, inside our cars, stroking our smartphones and tablets. Peel back the layers of illusion, and what remains is not a brain in a jar — however much we might fear or hunger for this — but a brain within a body, as remorselessly obedient to that body’s urges and limitations as any paleolithic hunter-gatherer.

It’s a point that has been emphasised by much recent research into thought and behaviour. To quote from Thinking, Fast and Slow (2011) by Nobel laureate Daniel Kahneman, ‘cognition is embodied; you think with your body, not only with your brain’. Yet when it comes to culture's cutting edge, there remains an overwhelming tendency to treat embodiment not as a central condition of being human that our tools ought to serve, but rather as an inconvenience to be eliminated.

One of my favourite accounts of our genius for unreality is a passage from the David Foster Wallace essay ‘E Unibus Pluram: Television and US Fiction’ (1990), in which he describes, with escalating incredulity, the layers of illusion involved in watching television.

First comes the artifice of performance. ‘Illusion (1) is that we’re voyeurs here at all,’ he writes, ‘the “voyees” behind the screen’s glass are only pretending ignorance. They know perfectly well we’re out there.’ Then there’s the capturing of these performances, ‘the second layer of glass, the lenses and monitors via which technicians and arrangers apply ingenuity to hurl the visible images at us’. And then there are the nestled layers of artificiality involved in scripting, devising and selling the scenarios to be filmed, which aren’t ‘people in real situations that do or even could go on without consciousness of Audience’.

After this comes the actual screen that we’re looking at: not what it appears to show, but its physical reality in ‘analog waves and ionised streams and rear-screen chemical reactions throwing off phosphenes in grids of dots not much more lifelike than Seurat’s own impressionist “statements” on perceptual illusion’.

But even this is only the warm-up. Because — ‘Good lord’ he exclaims in climax — ‘the dots are coming out of our furniture, all we’re really spying on is our furniture; and our very own chairs and lamps and bookspines sit visible but unseen at our gaze’s frame...’

There’s a certain awe at our capacity for self-deception, here — if ‘deception’ is the right word for the chosen, crafted unrealities in play. But Foster Wallace’s ‘good lord’ is also a cry of awakening into uncomfortable truth.

It reminds me of the scene in the film The Matrix (1999) in which Neo has to decide between taking the blue pill that will preserve his illusions, and the red pill that will reveal what his world actually looks like. He swallows the red pill, gulps a glass of water, and is led into another room. Nothing happens, until he reaches out to touch a mirror. Its surface shivers, sticks to his hand, then begins to flow over his skin like liquid cement, rising along his arm and down his throat. Choking, he screams — and wakes up somewhere else, naked, bald, gasping for air inside a cocoon filled with fluid.

It’s the perfect contemporary depiction of an atavistic fear: that the world around us is a lie. However, The Matrix is also a suitably ambivalent fable for modern times — because its lies aren’t supernatural tricks, but the apotheosis of human ingenuity. And the problem isn’t so much illusion itself as who’s in charge. The baddies here are the evil machines. But so long as we’re the ones running the show, it’s sunglasses, guns, and anti-gravity kung fu all the way, which is an infinitely more enticing destiny than unenhanced actuality.

What the red pill promises isn’t actually the real world at all. It’s the Matrix as it ought to be, knowingly bent to serve our desires: a dream of omnipotence through disembodiment.

Intelligence and Machines: Creating Intelligent Machines by Modeling the Brain with Jeff Hawkins


Here is another video lecture from Jeff Hawkins on the creation of intelligent machines through the modeling of the human brain. This lecture comes via UCTV and was delivered at UC Berkeley.

Jeffrey Hawkins is the founder of Palm Computing and Handspring. He has since turned to work on neuroscience full-time, founded the Redwood Center for Theoretical Neuroscience in 2002. He is the author of On Intelligence, with Sandra Blakeslee (a science ghost-writer that she gets her name on the cover, too).

For the record, and for the Nth time, we will never model the human brain in any real sense unless we can also model the human body in which that brain resides. Personality, identity, and consciousness are not confined to the brain, we are embodied creatures embedded in biopsychosocial environments. We can't even understand the body (or the brain for that matter), so there is little chance we will model it anytime soon.

Granted, this does not preclude creating intelligent machines, but they will be intelligent in a far different way that we are - and that might not be for the best.


Intelligence and Machines: Creating Intelligent Machines by Modeling the Brain with Jeff Hawkins
Are intelligent machines possible? If they are, what will they be like? Jeff Hawkins, an inventor, engineer, neuroscientist, author and entrepreneur, frames these questions by reviewing some of the efforts to build intelligent machines. He posits that machine intelligence is only possible by first understanding how the brain works and then building systems that work on the same principles. He describes Numenta's work using neocortical models to understand the torrent of machine-generated data being created today. He will conclude with predictions on how machine intelligence will unfold in the near and long term future and why creating intelligent machines is important for humanity.

TEDxToronto -- Ariel Garten -- Redefining Consciousness


Ariel Garten, CEO and Co-Founder of InteraXon, delivers a Talk at TEDxToronto 2011 on the theme of Redefining Consciousness.








From Wikipedia:
Ariel Garten is a Canadian artist, scientist and intellectual.[1] She was an avant garde clothing designer with a store called Flavour Hall (now closed) in Toronto, Canada. She is deemed to have made a "significant contribution to the field" [2] for her work in integrating art and science. She is pursuing cutting edge art and performances in other media, including dance, music, percussion, and cutting-edge instruments (such as hydraulophone, quintephone, and other). She creates work that explores the intersection of art and neuroscience.

Garten lectures about interdisciplinary neuroscience topics, such as "The Neuroscience of Morals" (on TVO's Big Ideas televised lecture series),[3] "The Neuroscience of Molecular Gastronomy" [4] and others), as well as psychotherapy and mental health.

Garten poineered Thought Controlled Computing Company Interaxon in 2007, which recently was honored at the Premier's Innovations Awards [5]
