Conscious computers are a delusion

Deutsch: Phrenologie

We have no reason to think computers will be anything other than complex devices that channel unconscious electrical impulses.

The notion that computers can think, or that one day they will do so, is rooted in one of two complementary misunderstandings. The first relates to the nature of computers and the second to the nature of thought. That these misunderstandings have had such a powerful hold on the minds of many otherwise intelligent people is due to a tendency to take useful metaphors – describing what computers do and how they do it – as literal truth.


Consider, first, misunderstanding about the nature of computers. Most people would agree that the computers we have at present are not conscious: the latest Super-Cray with gigabytes of memory is no less zomboid than a pocket calculator. But there is the feeling that at some stage, as a result of increasing computational power and in something called "complexity", the artefact that possesses this power and this complexity will wake up to its own existence, or at the very least, experience the transactions which take place in, through, and around it.

We should treat this claim with extreme scepticism because those who say that conscious computers are around the corner are not able to specify what features conscious computers will have in addition to those possessed by our current unconscious ones. There was a fashion in the 1980s and 1990s for invoking alternative architectures – in particular parallel rather than serial processing – as the basis for computers that would be aware of themselves. This fashion has now passed and the conceptual cupboard of the conscious-computers-round-the-corner brigade is now empty. We therefore have no reason for expecting that computers will be anything other than extremely complex devices in which unconscious electrical impulses pass into and out of unconscious electrical circuits and interact with any number of devices connected directly or indirectly to them.

As for thought, this has been even more profoundly misunderstood. Some have argued that thought does not require consciousness, so that computers can think, or will one day think, even though they will never be conscious. Thoughts, like other so-called conscious activities, are merely causal way-stations between inputs such as sense experience and outputs such as behaviour. They do not have to be conscious; indeed, consciousness contributes nothing to their causal efficacy. It requires no equipment or subtle argument to demonstrate that this is nonsense. All you need is to focus on the thoughts you are having now. To deny that thought is conscious is self-refuting: you cannot deny the consciousness of your thoughts without being conscious of doing so. And to claim that conscious thought, or indeed consciousness, has a central role in our lives belongs to an extreme behaviourism that is not able to explain even ordinary human behaviour.

Jennifer Egan, "Black Box" : The New Yorker

Few snippets from Jennifer Egan's excellent short fiction work, “Black Box,” in the June 4 & 11, 2012 issue of The New Yorker, The Science Fiction Issue.

-----

Some citizen agents have chosen not to
return.

They have left their bodies behind, and
now they shimmer sublimely in the
heavens.

-----

...Necessary ingredients for a successful projection: giggles; bare legs; shyness.

The goal is to be both irresistible and invisible.

When you succeed, a certain sharpness will go out of his eyes.


-----

Some powerful men actually call their beauties "Beauty."

Counter to reputation, there is a deep camaraderie among beauties.

If your Designated Mate is widely feared, the beauties at the house party where you've gone undercover to meet him will be especially kind.

Kindness feels good, even when it's based on a false notion of your identity and purpose.

-----

Posing as a beauty means not reading what you would like to read on a rocky shore in the South of France....

------

Eagerness and pliability can be expressed even in the way you climb from the sea onto chalky yellow rocks.

"You're a very fast swimmer," uttered by a man who is still submerged, may not be intended as praise...

------

...The directive "Relax" suggests that your discomfort is palpable.

"No one can see us" suggests that your discomfort has been understood as fear of physical exposure.

"Relax, relax," uttered in rhythmic, throaty tones, suggests that your discomfort is not unwelcome.
