An excellent commentary on Rationalist utilitarianism. One (among many) insight is the fallacy of grounding moral questions in arguments ‘from infinity’ Reminds me of Gregory Bateson’s systems theoretic argument that: “mere purposive rationality … is necessarily pathogenic and destructive of life”

Written in 2015, but what a remarkable illustration of the state (as a nexus of commerce, reputation management, and violent coercion) serving as a “cultural attractor”

I first learned dynamical systems theory from “Dynamics: the Geometry of Behavior” (1992), a collaboration between mathematician Ralph Abraham and artist Chris D Shaw. The book is over 600 pages long, and the visualizations stay strong and groovy the whole time.

OK, it finally happened! My new article, "Gradience as a cognitive principle for evaluating numerical notations", is now out today in @pnas.org. By focusing on numerals' use for communication instead of arithmetic, we have a new tool to assess their efficiency. www.pnas.org/doi/10.1073/...

Super stoked to announce that the preprint for my first PhD project is out! 🥳 In everyday life, we often rely on other people's opinions, despite them not sharing our exact preferences. But how do we do this adaptively? Find out in this 🧵 (1/7) or here: osf.io/e4g3q

🇺🇳 the UN just dropped their first report on AI governance. Discussion of governance as an enabler rather than hindrance — parallels with programs for vaccine equity (GAVI) and scientific coordination (CERN, EMBL). Regarding risks, they seem aware of vast unknown unknowns www.un.org/en/ai-adviso...
