The Future is Now: the Recession and the Steep Upward Slope

Brenda Cooper @ 17-11-2010

It’s a recession.  The housing market is tough, the job market is worse, and the country is so sharply divided we’ll be lucky if anything useful happens in Washington D.C. in the next two years.  Whole economies are backpedaling into austerity programs.  This does not feel like a ride up the steep right-hand curve of the emerging technological singularity.  But I think that’s where we are – in that place of so much change we can barely keep up, and in a time when many people are falling so far behind that they will never catch up.

The story of ourselves

Paul Raven @ 17-11-2010

The New Scientist CultureLab blog is running an interesting set of pieces about storytelling in the (post-)modern world (for which there is, regrettably, no single unifying tag or category to which I can link you); it’s probably due to a global swelling of interest in such matters coinciding with my own self-education curve, but in the last few years it’s felt like everything has started to boil down to narratives – the stories we graft on to our experiences so that we can make sense of the world.

Of course, by the terms of the theory, that is a narrative in and of itself… but before we get caught in an infinite loop of meta, let’s skip to this article that wonders how the changing structure of the narratives we produce in our art and culture will affect the ones we produce in our heads.

Gazzaniga [...] thinks that this left-hemisphere “interpreter” creates the unified feeling of an autobiographical, personal, unique self. “The interpreter sustains a running narrative of our actions, emotions, thoughts, and dreams. The interpreter is the glue that keeps our story unified, and creates our sense of being a coherent, rational agent. To our bag of individual instincts it brings theories about our lives. These narratives of our past behaviour seep into our awareness and give us an autobiography,” he writes. The language areas of the left hemisphere are well placed to carry out these tasks. They draw on information in memory (amygdalo-hippocampal circuits, dorsolateral prefrontal cortices) and planning regions (orbitofrontal cortices). As neurologist Jeffrey Saver has shown, damage to these regions disrupts narration in a variety of ways, ranging from unbounded narration, in which a person generates narratives unconstrained by reality, to denarration, the inability to generate any narratives, external or internal.

[...]

If we create our selves through narratives, whether external or internal, they are traditional ones, with protagonists and antagonists and a prescribed relationship between narrators, characters and listeners. They have linear plots with a fixed past, a present built coherently on it, and a horizon of possibilities projected coherently into the future. Digital technologies, on the other hand, are producing narratives that stray from this classic structure. New communicative interfaces allow for novel narrative interactions and constructions. Multi-user domains (MUDs), massively multiplayer online role-playing games (MMORPGs), hypertext and cybertext all loosen traditional narrative structure. Digital narratives, in their extremes, are co-creations of the authors, users and media. Multiple entry points into continuously developing narratives are available, often for multiple co-constructors.

These recent developments seem to make possible limitless narratives lacking the defining features of the traditional structures. What kinds of selves will digital narratives generate? Multi-linear? Non-fixed? Collaborative? Would such products still be the selves we’ve come to know and love?

As heady as these implications seem, we should not get carried away. From a literary perspective, digital narrative’s break with tradition will either be so radical that the products no longer count as narrative – and so no longer will be capable of generating narrative selves – or they will still incorporate basic narrative structure, perhaps attenuated, and continue to produce recognisable narrative selves.

Or, to put it another way, “we just don’t know, so we’ll have to wait and see”. But it’s fascinating stuff, if only for the tantalising offer of a place where literary theory, anthropology and hard neuroscience might one day all meet up… and that would be an awesome place to spend one’s life theorising, don’t you think? :)


I always knew they’d prove precognition was real!

Paul Raven @ 17-11-2010

Well, not really (or at least not for a long time), but I couldn’t resist the title. So, here are some bits from Wired Science‘s piece on Daryl Bem’s new paper entitled “Feeling the Future: Experimental Evidence for Anomalous Retroactive Influences on Cognition and Affect”… which purports to contain experimental evidence of precognition in human minds.

Bem’s experimental method was extremely straightforward. He took established psychological protocols, such as affective priming and recall facilitation, and reversed the sequence, so that  the cause became the effect. For instance, he might show students a long list of words and ask them to remember as many as possible. Then, the students are told to type a selection of words which had been randomly selected from the same list. Here’s where things get really weird: the students were significantly better at recalling words that they would later type.

[...]

The power of Bem’s paper is cumulative. In total, he describes the results of nine different experiments, conducted on more than 1000 subjects. All of the experiments revealed slight yet statistically significant psi anomalies, with an average effect size of 0.21 across all experiments.

However, the real contribution of this paper isn’t even these statistically significant results. Instead, it’s Bem’s attempt to create rigorous, well-controlled tests of psi that can be replicated by independent investigators. Because here is the dirty secret of anomalous phenomena like telepathy and clairvoyance: They’ve been demonstrated dozens of times, often by reputable scientists. (Bem is an extremely well-respected psychologist, best known for his work on self-perception.) Why, then, do serious scientists dismiss the possibility of psi? Why do rational people assume that parapsychology is bullshit? Because these exciting results have consistently failed the test of replication.

According to a footnote on that article, the process of replication (or at least attempted replication) has already begun, and there are links to two sets of negative results.

Now, I’m no psychologist or statistician, but even so, I’m going to maintain a skeptical stance on “psi powers”. While I have vague theories that there’s more to the universe and our place in it than we yet understand, I think the notion of clairvoyance or “seeing the future” is – at best – a massive oversimplification of the sort of quantum weirdness that makes our brains work the way they do, or – at worst – what happens when unlikely but possible lucky streaks intrude themselves into the world of statistical probabilities. (That “slight yet significant” bit always sets my skeptic bell to ringing; how do we know how slight something has to be before it isn’t significant?)

But then you already knew I was I going to say that, didn’t you? ;)


Stuxnet almost certainly meant to hobble Iranian uranium

Paul Raven @ 17-11-2010

Remember all the hypothesising about what the Stuxnet worm was supposed to do, and who had designed it for such? Well, the expert verdicts are in, and it appears Stuxnet was designed to very subtly sabotage uranium centrifuges by varying their rotation speeds in a way that, while hard to notice for humans, would effectively negate the enrichment process they are designed to perform.

So Iran’s Bushehr plant was almost certainly the target (or one target among many); and while we don’t have (and may never have) any substantive proof as to exactly who decided that they wanted to spoke Ahmedinejad’s nuclear wheels on the sly, I think we all know how the odds would fall if you were to pop down to your local bookmakers*.

Regardless of who did it, Stuxnet represents the opening of a particularly well-stocked Pandora’s box: highly-specific sabotage targetting of embedded (and potentially critical)  industrial systems. As Bruce Sterling points out, anyone who hadn’t thought of it before has certainly thought of it now. All the recent hyperbole describing the antics of patriotic  DDoS skript-kiddiez as “cyberwar” is gonna look pretty facile when stuff like Stuxnet becomes commonplace… which, with the benefit of hindsight, may have been the entire point all along.

Thermodynamic demonology: extracting energy from information

Paul Raven @ 16-11-2010

Here’s a potential plot device for one of Charlie Stross’ Laundry novels or, rather more seriously (though perhaps not as entertainingly), as the hinge for a Greg Egan story; a team of Tokyo researchers reckon they’ve managed to summon up a very tiny version of what physicists call “Maxwell’s demon”. Ars Technica breaks it down:

Maxwell’s demon has haunted thermodynamics for well over a century, since James Clerk Maxwell first suggested that a small demon might be able to selectively allow only hot atoms through a small gate, gradually extracting heat from a gas without expending much in the way of energy. But there’s no such thing as a free lunch, and the demon feeds on information: it needs to know which atoms are hot. Eventually, it was recognized that information was being exchanged for energy, and an equivalence between the two was calculated based on theoretical considerations. Until now, however, nobody has managed to build a demon that could help see how well real-world behavior matched the theory.

[...]

The metaphor the authors use is a spiral staircase. A particle placed on a small staircase will be buffeted by energy, and typically go up or down a stair; on average, it’ll go down more often than up, eventually settling at the bottom of the staircase. The demon stands at the side of the stairs with a barrier. When, by chance, the particle happens to move up to a higher energy state, it inserts the barrier behind it, preventing it from dropping down. Given time, the particle will reach the top of the staircase.

Their real-world implementation involves a bead on a tether that is able to freely rotate around a full 360° axis. Below the bead, the authors set up four electrodes that generated electric fields that were shaped like a sine wave. When the bead was in the trough of the wave, it would be at its lowest energy state. If the bead was jostled anywhere else, it gained potential energy that would eventually be lost again when it fell back down to the trough.

Remember, though, that not even demonologists get a free lunch:

If you ignore the apparatus involved, the authors could directly compare the energy gained against the amount of information required to flip the switches involved. And the results appear to agree very well with the theoretical predications.

As far as thermodynamics is concerned, however, you have to consider the apparatus, since it’s necessary to balance the books in order to avoid thinking that we’re getting energy for free. And, as it turns out, the system for tracking the bead and switching currents is rather elaborate, involving “microscope by constructing a real-time feedback system including video capture, image analysis, potential modulation and data storage.” As an accompanying perspective notes, you’d probably also have to throw in the energetic cost of the grad student who was operating the whole thing, too.

So, no chance of heating my garret with information, then… unless I burn all my books. (Not. Gonna. Happen.)
