Life, The Universe & That Safety Thing

Exploring what it means to be human in an age of artificial intelligence. Essays on evolution, philosophy, and building a future worth living in.

Hello, I'm Sean

I write about AI safety, philosophy, and whatever else catches my attention. Currently working on mapping the space of AI risk arguments with the Doom Assumptions project.

Featured Project · AISC 2026

An interactive map of AI risk arguments. Different worldviews, one shared structure. Set your own probabilities, compare named worldviews (Yudkowsky-like, LeCun-like, Hinton-like, …) and find cruxes automatically.
