As We May Think

Quick note:
The tech terminology at first confused me, and if you are like me the following list might help you. Please feel free to correct me if I’m wrong:

  • Photocells are light sensors. Advanced versions of these are in your smartphone and digital cameras, behind the lens.
  • Thermionic tubes = vacuum tubes. Incandescent light bulbs are a type of these. Along with relays, these were among the essential components of an electric circuit until transistors became popular.
  • Cathode ray tubes = CRT (old fat screens)

The article was published in a time where the industrialization we discussed regarding last week’s readings is quite in its adult phase; “the humble typewriter, or the movie camera, or the automobile” are, rather than new innovations, things that “perform reliably.” In a war-winning United States, not without the help of mobilized scientists, Bush proposes a vision of using technology to deal with the problem of ever-increasing human knowledge that “extended far beyond our present ability to make real use of the record.” He is anticipating computers to be used in the information age, Thomas P. Hughes (2005) describes (p. 97). His picture of the “memex”, which is essentially a microfilm browser with editing and sharing functions, seems a bit different from what computers actually became- but it was 1945, and digital computing was not really a thing. What is impressive is his insights on how information should be dealt with.

Using the example of Mendel’s work not reaching potentially significant contemporary readers, Bush defines the problem faced by humans as the inability for the actual use of (scientific) knowledge to keep pace with the speed that its records expand. According to him, three aspects could use some improvement and will do so regarding scientific records: creation of new ones, storage and retrieval.

Instead of trying to guess what the next new technology will be, Bush describes in detail how the current technology could develop and be used for the above goals. Storage will be faster, easier, cheaper and smaller. Note that he emphasizes that “[c]ompression is important … when it comes to costs.” With a little stretch, his idea that smaller size will lead to massive reproduction is in a way analogous to the shrinking space of railway times leading to the access to a much larger geographical space.

Creating new records could also become easier, through such developments as speech recognition and automated input. The automation of repetitive processes that are currently limited to arithmetic equations would extend to higher-level symbolic logics and advanced data analysis. And the access to specific data, which Bush calls selection, also could be much faster if we applied the selection process of, say, the telephone switching system and improved it using electronics. So the storage, input and retrieval of knowledge would all become faster and allow for a much larger quantity.

Then Bush pictures a device, “memex”, that embodies the above improvements along with an additional crucial idea, association. Unlike the current indexing systems, which are mostly alphabetical or numerical categorization, a new system would enable the direct connection of two or more different pieces of information; allowing for the association between thoughts which is how the human mind works, hence the title of the article. His example of the Turkish bow researcher describes knowledge pieces that are interconnectible via a code space separate from the content and allow long-term storage, commenting/editing/creating from the user’s part, browsing, copying and sharing. This idea is viewed as the initial concept of hypertext– one of the main structures of internet (Landow, 2006, p.11)

His “new forms of encyclopedias” filled with “a mesh of associative trails” incredibly seem to be referring to Wikipedia. He expresses the hope that humankind would be able to stand on the shoulder of giants and go beyond its application of control over the environment and war against each other, in order to “grow in the wisdom of race experience.”

The article portrays several ideas that we can associate with current things: the hypertext and links, of course, but also here and there we find mentions of potential Google Glass, Siri and big data analysis. Just before the end of the article, we can also peep at Bush’s version of cyborg future, where information could be transmitted to and from the brain directly using electric signals rather than being translated to sensory phenomena; this sounds like his sci-fi imagination, which he has been suppressing throughout the article, finally going off… But in a sense this also has been realized: not exactly (well, not yet) by connecting wires to the nervous system, but by the vast network of computers and the digitization of all information.

  • It is worth noting his limited use of female words, only associated with certain jobs: stenotypist, typist, “simple key board punches” operators, and (not specified but probably) file clerk. This seems almost like a repeat of something that happened in Marx’s era: as machines enter the labor space, so do women- but not on equal terms. A further interesting point is that as Wendy Chun (2004) points out, computers in early 20C referred to human operators of the machines, mostly young women; “they were also considered to be better, more conscientious computers, presumably because they were better at repetitious, clerical tasks”¬†(p. 33).
  • Bush was administrator for the wartime U.S. military R&D, which I can’t imagine had no influence on his ideas regarding the inefficiently increasing knowledge. The initial version of internet was funded by the U.S. department of defense. The steam engine came out of an industrial need, like a lot of innovations happening in the tech industry today. Although this might be a rough statement, I feel not too much off target by arguing that a lot of initiative regarding technological change comes from either the military or the industry. What are the implications here? How relevant are the sources of technological changes?
  • Are we better off with the internet? I mean, I love the internet. But more globally, what would be the implications? While there are claims that the hypertext as a system that allows for easier participation in creative activities and dissolves the boundaries between author and reader, it “has the potential … to be a democratic or multicentered system” (Landow, 2006, p. 343), last class we also talked about how some corporations are exploiting that type of collaborative and/or voluntary work that the medium enables us to do. Is the capital intercepting the ‘revolutionary potential’ and use it for profit?
  • Are we any wiser? To be more specific, has our ability to process information caught up with the ever-increasing rate of knowledge production? Or are we being disoriented by the influx of information? In the case of the latter, is it a transitional thing, just as the coach travelers were disoriented by the speed of the railway?

Also, this video featuring Douglas Engelbart, who was inspired by Bush, might be interesting to watch alongside the article. It is perhaps most famous for the use of a computer mouse, but it also introduces important features of computers that now seem so natural, including the hypertext.
