Computers produce virtuality only - no way they show consciousness

A computer, no matter how fast and complex it might be, will at best simulate consciousness and imitate intelligence since - by the way a computer is constructed and used today – the computer is a generator for objects and states in a virtual reality. Virtual reality adds to but does not overlap with the physical reality (corporeality) of our everyday life. Intelligence and consciousness are products of corporeality and are therefore separate from the virtual world computers produce and play in. The border between these realities is sharp and clear and can not be transcended. As long as a computer is the medium for a simulation, imitation, visualization it will produce objects well within the virtual world. It will never produce intelligence or show consciousness. But is the computer doomed to be a medium only? No. Aren't our brains also just media for the play of sensations, thoughts, feelings? No. The difference lies in the way of operation. Todays computers have separat...

Consciousness - an emergent property

A stone is dropped into a pond creating a perfectly circular wavefront that propagates radially away from the point of impact. The speed of wave-propagation, the amplitude and wavelength can easily be modelled by a wave-function - a computer can simulate the wave-pattern on the water and display a virtual lake with breathtaking similarity. But it remains a simulation. The lake does not solve a wave-equation in order to show a wave-pattern. The propagation of a water-wave is the consequence of an inherent property of the water itself. The description by a wave-equation - as accurate as it might be - is a model of the real thing, a simulation - not even an imitation. These are two completely different - and absolutely not comparable - paths to the image of a water-wave. The simulated wave shows the same imagery as the real one, the wave-propagation looks identical, the optical reflections will be perfectly similar, it might even be possible to predict some wave-behavior. But the simula...

Artificial Intelligence Revisited

On June 22, 2010 David Gelernter presented his thoughts on Artificial Intelligence - the capability of computers to show intelligent behaviour - in a talk on invitation by The American Academy and FAZ in Berlin. The title "Dream Logic, Software Minds, and the Poetry of Human Thought" gave a hint at what to expect. He went deep into his rather personal understanding of intelligence and consciousness. Gelernter attempted a definition of 'thinking' (as opposed to the simulation of thinking) by deep introspection and analysis of his thought-processes. The result was a rather romantic, very anthropocentric praise of creativity, dreaming and intuition. Something tightly connected to feelings, emotion and unpredictability - a collection of elements a computer does arguably not have. A thinking computer, he inferred, should 'know' or 'feel' that he is thinking - thereby connecting thinking to consciousness. But is this the right approach? David Gelernter...

The stuff in the web is not information - it is data

Thousands of blogs copy snippets from different sources, sometimes enrich them with comment (more often they don't), repost, redistribute, recycle. Twitter plugs up the net with autistic-looking short-messages and a seeming gazillion applications allow users to automatically cross-contaminate social networks with annoying status-messages. It is natural that many are  looking for ways to survive the 'information-tsunami' of the ever-growing web. While filtering for keyphrases is the usual way out, David Gelernter sees hope in exchanging the axis along which the web-babble should be ordered: let's use the time axis (see "Time to start taking the internet seriously" on edge.org). Reminiscent of twitters lifestreams, information would visually flow from future over present to past letting the reader focus on everything in the timewindow she chooses. Aside from the big questionmark (why would such a reshuffling make lifestreams easier to bear?) there is a major mi...

Meta-Mining

Some so-called 'internet-prophets' bemoan the increasing volume of web-babble, the deluge of chatter, the hollowness of the information-tsunami. Big words of cultural pessimism that are gratefully picked up by the media. Those web-critics have a serious problem: they try to *read* all that. Would they go into a library and start reading the very first book on the shelf? I hope not. When they open Encyclopedia Britannica (yes there are some printed versions around) do they start reading on page 1? Some try to survive in the web by suggesting a new order of information - an ordering according to the date of appearance - the life-streams ( see David Gelernter on Edge.org ) . This would be an order in time instead of 'space' (where data are conventionally mapped out in different 'locations' on your screen or hard-drive).This approach to clean the data-mess is reminiscent of the cleansing of Augias' stables by diverting the River Alpheus. It's an honorable...

You don't want an i-Pad? You are getting old!

The old tecchies recite their mantra of 'if you can't open it, you don't own it'. They lament that the i-Pad has no keyboard, no CD-drive, no printer connection - they miss the bundle of wires that make a computer a computer. "The original Apple ][+ came with schematics for the circuit boards, and birthed a generation of hardware and software hackers who upended the world for the better", writes Cory Doctorow on boingboing.net " Why I won't buy an iPad (and think you shouldn't, either) ". Well, sure. We are getting old and we say what we hated to hear our parents say when they got old: "those were the good old days". You remember when you were able to repair your car by yourself - everything? When your telephone went silent - with a bit confidence and a drop of oil you could get it ring again. And the radio, yep, a flip against the coil, a resolute puff over the tunable capacitor, some dust-clouds - done! Todays devices are ...

One Culture

The distinction between ‚two cultures' is artificial and deleterious, as is argued in ‚ Wissenschaft ist keine Kunst ' („Science is not Art") by Rapoport and Hucho . Clearly, Humanities are concerned with understanding while the Sciences look for explanations – but the different focus can neither be reason nor excuse for a separation in disjunct categories of culture. The real difference obviously is the different public appeal, the difference in popularity. While humanities can be chatted about even without deep understanding – just as a piece of music can be enjoyed without any understanding of an underlying theory – this is impossible with science. There can be Pop-music, pop-Humanities but no Pop-Science.
