Meta's former chief AI scientist. He has been exploring the potential of a Joint-Embedding Predictive Architecture (JEPA) since 2022, a less literal approach to building world models that focuses on modelling complex environments—both physical and virtual—rather than simulating real spaces directly.
In November 2025 he left Meta to work on this problem full time. His startup, Advanced Machine Intelligence, plans to turn his ideas into reality, starting with a partnership with Nabla, a health-tech startup. He says the goal is a system which uses its own world model to work out "what sequence of actions will optimally accomplish a task that I'm setting".
I didn't know he was dead; I thought he was British.
