How close are we to superintelligence? Closer than I thought in February. New evidence forced me to revise my prediction: perhaps within a year, not five. My interview with @ucsandiego.bsky.social Today on why, and on what an exciting and frightening moment this is. today.ucsd.edu/story/how-cl...

Career update: as of July 1, I hold a joint appointment at UC San Diego, in the Halıcıoğlu Data Science Institute and the Department of Philosophy. Grateful to colleagues in both schools. It's an exciting time for philosophy of science and the foundations of AI. More soon.

Grateful to @apaphilosophy.bsky.social for highlighting my @nature.com Comment coauthored with Mikhail Belkin, Leon Bergen, and David Danks. We argue that the artificial general intelligence (AGI) has arrived, and the evidence is clear.

My paper with Roderich Tumulka is featured in @newscientist.com! We prove that the quantum state of the universe is, in a sense, fundamentally unknowable. Nature keeps its deepest secrets.

Does AI already have human-level general intelligence (AGI)? Our answer in @nature.com today: Yes, AGI has arrived. The evidence is clear. www.nature.com/articles/d41...

Does AI already have human-level intelligence? The evidence is clear
The vision of human-level machine intelligence laid out by Alan Turing in the 1950s is now a reality. Eyes unclouded by dread or hype will help us to prepare for what comes next.

Excited to give "AI Meets Philosophy of Science" talks in Arizona—today at @arizonastateuni.bsky.social , next Fri at @uarizona.bsky.social . Why does ML work so well? I argue it reveals abundant learnable structure in nature, motivating an expanded view of laws beyond fundamental physics.

Very happy to share that my paper coauthored with Rodi Tumulka has been accepted for publication in The British Journal for the Philosophy of Science! The result was unexpected and points to fundamental limits on knowledge in a quantum universe. arxiv.org/abs/2410.168...

My paper, “The Simplicity of Physical Laws,” is now out in Noûs. One of the hardest problems I’ve worked on. The solution came as a surprise. It’s also shaping my current thinking about the foundations of AI. Link: onlinelibrary.wiley.com/doi/10.1111/...
