Who he is

Affiliation: Co-founder & Chief Scientist, Physical Superintelligence PBC ("PSI") — launched publicly 2026-09-01 with a $58M seed round (co-founders Matt Pines, CEO, and Alex Klokus; PRNewswire, 2026-09-01). Previously founder of Gemedy; Harvard PhD (physics); MIT background; co-host, Moonshots podcast (with Diamandis, Blundin, Ismail); co-author with Diamandis of Solve Everything (Feb 2026); writes the daily AI newsletter The Innermost Loop (~100K readers).
One-line position: Intelligence is a physical phenomenon — maximizing future freedom of action — and AI capability follows from compute, data, and algorithmic insight more than from any specific architecture; reason about it quantitatively, not narratively. New corollary (2026): aim superintelligence at physics itself and it "solves everything else."

Discipline & technical bet

Physicist by training ("causal entropic forces": intelligent behavior as maximization of future option space — Physical Review Letters, 2013). The concrete wager now is no longer academic: PSI is a public benefit corporation staffed with "virtual physicists" (AI agents doing physics research), betting that AI can industrialize the discovery of new physical laws — near-term product: data-center design optimization; long-term: new physics across the energy-to-compute spectrum. He has, in effect, turned his 2013 theory of intelligence into a funded company.

Key claims (Says)

Notable predictions — with falsifiable checks

Revealed behavior (Does)

Feels

Wants the universe to be legible — and wants to be the one who made it computable. The move from theory to company suggests impatience with being the smartest commentator in the room; he wants a result with his name on it.

Hears

Frontier-lab research output daily (he digests it for 100K readers); the Diamandis abundance network; now also his cap table — Breakthrough Energy and deep-tech investors expecting physics, not essays.

Sees

The whole AI literature at newsletter cadence — few people metabolize more papers per day — plus, now, whatever PSI's internal agents produce. His vantage: pattern-matching across physics and ML before either community connects the dots.

Incentive map

Changed materially in 2026. Previously the low-conflict calibrator of the Moonshots crew (v1 gave him extra weight per CONVENTIONS rule 25). Now: equity in a $58M-funded AI-physics startup, a co-authored abundance book to sell, and a large newsletter audience. He can no longer easily say: that AI-for-science is overhyped; that world models are far off; that the Singularity-aimed-at-everything frame overpromises. Rule 25 discount now applies to him at full strength — grade his AI-for-physics claims like Diamandis's longevity claims.
