  • Rejected papers still count against the monthly quota, and the computer science category alone has sextupled over the past decade.

  • Three government policy documents in the past year — from ENISA, South Africa, and the White House — shipped with fabricated AI-generated citations.
  • A 2023 study cited in the piece found 55% of GPT-3.5 citations and 18% of GPT-4 citations were entirely fabricated.
  • Stanford's Rachel A. George argues verification belongs in the publishing pipeline: automated citation checks, AI disclosure standards, and trained human reviewers.

There is also worrisome evidence that Effective Altruism's pivot from a core focus on "distributing bed nets to help poor people survive malaria" to a core focus on "funding think-tanks dedicated to worrying about if AI will kill us all" might have been a planned bait-and-swit…

Recent commentary

🌱 "The Ecologies of Algorithmic Machines" is almost ready. This book draws on over three years of research into the supply chains of AI, offering a historical analysis of its materiality and environmental-making regimes while challenging the dichotomy between nature and algorithmic machines.

🌻 For my upcoming book, The Ecologies of Algorithmic Machines, I created a diagram that illustrates the different phases (and corresponding chapters) exploring the materiality of AI. Please feel free to share and cite it if you find it useful. I'd also welcome feedback to improve the diagram.
