Ancient, 80-year-old machinery could hold the secret to maximizing AI capabilities in today's world

In the 1940s, an American engineer named Vannevar Bush was trying to solve a problem related to research. At that time, anyone looking for articles, books, or scientific records had to go to a library and search through index cards. This laborious process was the focus of Bush's attention, and he saw potential in existing systems for handling data like punched cards.

Bush, who was the dean of the school of engineering at MIT and the president of the Carnegie Institute, proposed a solution to the research problem called the "memex". This personal device, built into a desk, would rely on microfilm for data storage. The memex would include a form of associative indexing for tying two items together, allowing users to click on a code number and jump to an associated document or view them simultaneously.

Bush's vision was first published in his influential essay, "As We May Think", which was published in The Atlantic in July 1945. In this essay, Bush foresaw the development of "powerful mechanical aids" to help with repetitive thought, and today we are automating far more thinking than was ever possible with a calculator. This isn't far from today's Wikipedia.

However, Bush believed that a purely technical solution like the memex is not enough, and technology should still be human-centered, underpinned by a philosophical vision. Bush's essay suggests that the added value in the memex lay in making it easier for users to manipulate ideas and spark new ones, drawing a distinction between repetitive and creative thought.

Bush's vision of the memex inspired American inventors Ted Nelson and Douglas Engelbart to develop hypertext systems in the 1960s, which formed the foundation of the world wide web. Bush's concerns about the impact of technology on human creativity and reasoning still feel strikingly relevant today. In his 1970 book, Pieces of the Action, Bush expressed concerns that technology had largely missed the philosophical intent of his vision, with machines now thinking for us or controlling us.

Bush was born in Everett, Massachusetts, USA. During the second world war, he was the director of the Office of Scientific Research and Development. Bush died at the age of 84 in 1974, but his concerns about the impact of technology on human creativity and reasoning still resonate today.

Bush's essay also predicted that new forms of encyclopedias would appear, ready-made with a mesh of associative trails running through them, ready to be dropped into the memex. Creating copies or excerpts was a tedious, manual task, but Bush believed that the memex would make this process much easier.

In summary, Vannevar Bush's vision of the memex was a precursor to the digital information age we live in today. While the memex was not realised in its entirety, its ideas have influenced the development of hypertext systems and the world wide web. As we continue to automate more and more thinking, it is important to remember Bush's concerns about the impact of technology on human creativity and reasoning.
