Essay by Collin Jennings: “..But now Google and other websites are moving away from relying on links in favour of artificial intelligence chatbots. Considered as preserved trails of connected ideas, links make sense as early victims of the AI revolution since large language models (LLMs) such as ChatGPT, Google’s Gemini and others abstract the information represented online and present it in source-less summaries. We are at a moment in the history of the web in which the link itself – the countless connections made by website creators, the endless tapestry of ideas woven together throughout the web – is in danger of going extinct. So it’s pertinent to ask: how did links come to represent information in the first place? And what’s at stake in the movement away from links toward AI chat interfaces?
To answer these questions, we need to go back to the 17th century, when writers and philosophers developed the theory of mind that ultimately inspired early hypertext plans. In this era, prominent philosophers, including Thomas Hobbes and John Locke, debated the extent to which a person controls the succession of ideas that appears in her mind. They posited that the succession of ideas reflects the interaction between the data received from the senses and one’s mental faculties – reason and imagination. Subsequently, David Hume argued that all successive ideas are linked by association. He enumerated three kinds of associative connections among ideas: resemblance, contiguity, and cause and effect. In An Enquiry Concerning Human Understanding (1748), Hume offers examples of each relationship:
A picture naturally leads our thoughts to the original: the mention of one apartment in a building naturally introduces an enquiry or discourse concerning the others: and if we think of a wound, we can scarcely forbear reflecting on the pain which follows it.
The mind follows connections found in the world. Locke and Hume believed that all human knowledge comes from experience, and so they had to explain how the mind receives, processes and stores external data. They often reached for media metaphors to describe the relationship between the mind and the world. Locke compared the mind to a blank tablet, a cabinet and a camera obscura. Hume relied on the language of printing to distinguish between the vivacity of impressions imprinted upon one’s senses and the ideas recalled in the mind…(More)”.
