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.
