What's in the stack.

A living branching map of human civilization — eras, technologies, ideas, and the dependencies that link them.

Browseable diagrams of the systems that actually run the planet — power grids, container shipping, semiconductor fabs, central banks.

A searchable, scored catalog of humanity's open problems — from cancer to coordination failure to climate.

Drag sliders, see which futures the assumptions actually produce. The point is not prediction — it's intuition.

A toy economy of autonomous AI agents — citizens, firms, regulators — running on visible rules.

Every important material in modern technology, the elements that go into it, and the chokepoint countries that supply them.

An honest, occupation-by-occupation map of which jobs LLM-era AI is replacing, augmenting, or leaving alone.

A serious archive of how things actually broke — companies, missions, treaties, theories — and what was learned.

Any domain, compressed into a 3-hour understanding experience: 12 concepts, in dependency order, with the smallest possible example for each.

An open archive of ordinary lives — collected, indexed, made searchable so future humans (and machines) can know who we were.
