Computers "remember" things in the form of discrete entries: the input of quantities, graphics, words, etc. Each item is separable..., perhaps designated by a unique address or file name, and all of it subject to total recall. Unless the machine malfunctions, it can regurgitate everything it has stored exactly as it was entered, whether a single number or a lengthy document. This is what we expect of the machine. Human memory, on the other hand, is the invisible psychic adhesive that holds our identity together from moment to moment. This makes it a radically different phenomenon from computer memory. For one thing, it is fluid rather than granular, more like a wave than a particle. Like a wave, it spreads through the mind, puddling up here and there in odd personal associations that may be of the most inexplicable kind. It flows not only through the mind, but through the emotions, the senses, the body. We remember things as no computer can--in our muscles and reflexes: how to swim, play an instrument, use a tool.LESSATTRIBUTION DETAIL »
Your brain receives, stores, and processes information, dispenses results, and controls your biological equipment. When properly p...rogrammed, computers can do likewise, except that they control electromechanical rather than biological equipment. Beyond these functional similarities, computers and brains have virtually nothing in common. To begin with, the electronic circuits in a computer are not analogous to brain cells. The two differ in appearance, in structure, and in principles of operation. The key functions of information storage and information processing are served in computers by physically different components. In a typical computer, one finds separate CPU and memory units; but even in computer designs where processing circuits are intermixed, the two functions remain distinct. In the brain they are not distinct; they're distributed throughout the brain and intermixed in ways that we don't understand.LESSATTRIBUTION DETAIL »
A computer does not think, it feels nothing, and what it is said to "know"--bits of information all cast in the digital mode--has ...no fringe. Nor has it a memory, only storage room. On any point called for, the answer is all or none. Vagueness, intelligent confusion, original punning on words or ideas never occur, the internal hookups being unchangeable; they were determined once for all by the true minds that made the machine and program. When plugged in, the least elaborate computer can be relied on to work to the fullest extent of its capacity; the greatest mind cannot be relied on for the simplest thing; its variability is its superiority.LESSATTRIBUTION DETAIL »
Most of the brain consists of "wires"; a single unit may have thousands of connections with other units and with itself. That is n...ot the case in a standard computer, where a chip usually has less than six connections. Moreover, neurons are much, much slower than the switching elements of the computer. It seems likely that the brain can accomplish its complex feats of perception and thought by means of millions of connections acting in parallel. The connections as a whole define the information content of the system. In this way a vast amount of knowledge can be brought to bear on a decision all at once. The brain seems to be able to perform as many as two hundred trillion operations in a second; not serially, but simultaneously.LESSATTRIBUTION DETAIL »
The child receives data through the sense organs; the child also has some inborn processing capacities--otherwise it would not be ...able to learn--but in addition, some "information" or "programs" are built-in at birth (for example, the child does not have to learn how to suck, for this is an innate reflex); there is a working memory, in which the child keeps those items of knowledge that are being used at a particular moment; and there is a permanent memory, which is, in Locke's terms, largely a "blank tablet" at birth, but which has a storage capacity that makes a hard disk pale into insignificance. The child gradually builds up a symbolic representation of the world around it, so there must be some inner "language" or medium of representation; even a newborn baby is starting to see and taste and smell and hear and touch, and to remember the more striking of its experiences, so the internal medium by which it represents and stores these impressions cannot be the native language (of which it is still ignorant. Jerry Fodor [in The Language of Thought] has discussed this inbuilt "language of thought," which is similar conceptually to the "machine language" that is built into the personal computer and about which most users remain completely ignorant).LESSATTRIBUTION DETAIL »
Despite many assertions to the contrary, the brain is not "like a computer." Yes, the brain has many electrical connections, just ...like a computer. But at each point in a computer only a binary decision can be made--yes or no, on or off, 0 or 1. Each point in the brain, each brain cell, contains all the genetic information necessary to reproduce the entire organism. A brain cell is not a switch. It has a memory; it can be subtle. Each brain cell is like a computer. The brain is like a hundred billion computers all connected together. It is impossible to understand because it is too complex. As Emerson Pugh wrote, "If the human brain was so simple that we could understand it, we would be so simple that we couldn't."LESSATTRIBUTION DETAIL »
Bias entails a value-directed departure from accuracy, objectivity, and balance--not just a distorted presentation of facts. If, f...or example, a reporter fails to notice that the computer has swallowed a crucial paragraph in a news story, and the story is published without the paragraph, the inevitable distortion results from error, not bias. For a story to be biased, the distorted information it contains must be causally connected to the writer's or editor's values.LESSATTRIBUTION DETAIL »
One difference between humans and computers lies in the relative strengths in their respective abilities to understand symbolic re...lationships and to learn facts. A computer can remember billions of facts with extreme precision, whereas we are hard pressed to remember more than a handful of phone numbers. On the other hand, we can read a novel and understand and manipulate the subtle relationships between the characters--something that computers have yet to demonstrate an ability to do. We often use our ability to understand and recall relationships as an aid in remembering simple things, as when we remember names by means of our past associations with each name and when we remember phone numbers in terms of geometric or numeric patterns they make. We thus use a very complex process to accomplish a very simple task, but it is the only process we have for the job. Computers have been weak in their ability to understand and process information that contains abstractions and complex webs of relationships, but they are improving.LESSATTRIBUTION DETAIL »
The Hacker Ethic: Access to computers--and anything which might teach you something about the way the world works--should be unlim...ited and total. Always yield to the Hands-On Imperative! All information should be free. Mistrust authority--promote decentralization. Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position. You can create art and beauty on a computer. Computers can change your life for the better.LESSATTRIBUTION DETAIL »
Both instruments are processors of information. Both appeared when nothing quite like them had existed before, and both began to m...ake their effects felt immediately (a situation that isn't invariable with new technology). Both devices were less the result of a single breakthrough than of an evolving set of technologies. Like the computer, the printing press had no one certain inventor; it was a technology whose time had come.LESSATTRIBUTION DETAIL »
