Thinking in Primitives: A mental model to dissect the foundations of Civilization, Humanity & Creativity

Thinking in Primitives: A mental model to dissect the foundations of Civilization, Humanity & Creativity

Understanding the building blocks of the world around us that unlock creativity and innovation

The most important innovations are invisible. Yet they are reliable building blocks of creativity that fuel human imagination.


The same 26 letter alphabet lets Shakespeare write a play, a researcher publish science or you can text your mum.

A standardised screw thread lets you build a house, a car or a space station.


This is the story of primitives; the fundamental components that make everything else possible. We explore how Jeff Bezos coining the term "Thinking in Primitives" as he invented AWS to the building blocks of the universe and life in it.


Join our tour through the weird and wonderful ideas of history as we gather ideas for how to build the future of humanity, space technology and anything you can imagine.


You'll learn:

  • By breakthroughs depends on invisible primitives created by someone before you
  • Why the most valuable opportunities are the ones everyone uses but nobody sees
  • How to identify foundational building blocks in any industry before competitors do
