📚 The AI Era Series · 4-Book Diagnostic

Four diagnostic axes

Data → mechanism → meaning → history. Four questions live in the same era at once. One book per question.

① Measure
P1 AI Class Society

What is happening

Hiring +92% / -21%. Wage +56%. The inflection in numbers. Without measurement, all debate is guesswork.

② Diagnose
P3 Quiet Erosion

Why it happens

Cognitive Atrophy / Expertise Debt / Trust Erosion. The mechanism behind the divide. No prescription without diagnosis.

③ Redefine
P4 Things We Haven't

Who we are

Consciousness, emotion, relationship — the words shift. Where function arrived first, meaning has to follow.

④ History
P5 Facing Machines

Is this the first time

Luddites 1811. AI layoffs 2026. The same place, 200 years apart. The second time it has a name.

The first book for your role
