The Three Eras
Blue collar, white collar, blank collar — and the shift that defines the intelligence age.
A look at what’s inside · 8 pages
What it is
Every age of work has had its collar: a shorthand for how a generation creates value. The industrial age built with the hand. The information age built at the desk. The intelligence age belongs to the worker who directs the machine instead of becoming one.
This field guide lays out the pattern in plain language — where value has moved, why it is moving again, and what the blank collar actually does differently. It is the fastest way to understand the thesis the whole school is built on.

- 04The three movesHow the shift from white to blank collar actually starts — in behaviour, not a job title.
