@sellathechemist there's a clock outside Corpus Christi College in Cambridge named that, for good reason: www.johnctaylor.com/the-chronophage

The Chronophage - John C Taylor
The Chronophage is one of the things I’m most proud of. ‘Chronophage’ is derived from the Ancient Greek words ‘chronos’ and ‘phage’, meaning ‘time-eater’. The creatures that stalk the top of the clocks will continue to eat time for hundreds of years to come, so the majority of the construction is in stainless steel, gold and enamel, chosen for their longevity. When I returned to Cambridge in 1999, I found the undergraduate library was unchanged since I was a student in 1956. I decided to offer my former college – Corpus Christi – sufficient funds to transform the adjacent bank […]

Abstract  Large-language models (LLMs) are rapidly becoming part of human culture, reshaping how information is produced, transmitted, and used. Here we propose that their diffusion can be understood through a viral analogy, with LLM use spreading through populations, becoming embedded in cognitive and cultural practices. We model transitions among uncoupled, coupled, and persistently dependent users, and show that the interplay between social transmission, recovery, and collective reinforcement can generate tipping points and technological lock-in. A central consequence is the possibility of runaway dynamics: once a critical threshold is crossed, small increases in adoption can trigger rapid population-level shifts toward persistent dependence, with abrupt losses in cognitive competence. The same framework, however, identifies conditions for cognitive immunization, based on reducing transmission and facilitating reversibility. Our results highlight how LLM adoption may involve nonlinear collective transitions with important consequences for cognitive autonomy.
