Key positions

AI arrives into a productivity-starved, demographically-declining economy — its net effect is strongly positive.
‘Task loss’ is the correct unit of analysis for AI’s impact on labour; jobs outlast individual tasks.
Multi-domain specialists (‘E-shaped’ or ‘F-shaped’ people) will be disproportionately valuable.
AI is the first universal one-on-one tutor (Bloom’s 2 Sigma), democratising elite education.
On moats and AI industry structure: complex adaptive system; confident early predictions are historically near-universally wrong.
Self-identifies as an ‘indeterminate optimist’ — bets broadly rather than on a single determinant outcome.
Institutions are best understood through who actually controls them, not their formal charter — a small organised minority (Iron Law of Oligarchy) typically holds real power, and public consensus can be manufactured through mutually reinforced private lying (Common Knowledge‘s preference-falsification section).
Content-moderation infrastructure, once built for narrow cases, tends to be annexed for broader use by whoever can pressure the company holding it — his ‘ring of power’ account of platform censorship.
Backs 'Little Tech' — small, structurally unencumbered companies — as best placed to rebuild products around AI, versus incumbents constrained by the innovator’s dilemma.
