The Civilizational Stack of Intelligent Tools

The Civilizational Stack — Historical Pattern

Five prior technologies through seven layers. Each traversal faster than the last.

Five technologies, seven layers, each faster than the last

Writing, maps, electricity, the computer, and search each traversed the same seven-layer stack. Each took less time than the one before it. The acceleration is monotonic, and it points somewhere.

Writing

~5,000 years

L1–2Uruk proto-cuneiform (~3300 BCE)

L3–5Hammurabi's Code → Gutenberg press

L6–7Pacioli's ledgers → scientific journals

Maps

L1–2Cadastral tablets → Portolan charts (1270)

L3–5Ordnance Survey → Google Maps

L6–7Prime Meridian (1884), Landsat

Electricity
