📚 The AI Era Series · Five Books

Five lenses on
the AI era at work

Measure. Diagnose. Redefine. Re-historicize. Strategize. Five lenses on the same window. When one book cannot hold an era, you write a series.

Five books, five diagnostic axes

Five scalpels on the same data. From measurement to strategy — each book opens one axis of the era.

Five diagnostic axes

Data → mechanism → meaning → history → strategy. Five 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.

⑤ Strategy
P7 SEO Is Dead

What to do about it

SEO → GEO. When AI replaces search, the 90-day playbook for brand survival. After diagnosis comes prescription.
