The Local-First Exocortex: Run a Private LLM on Your Notes

Godlike Intelligence as a Moral Imperative

We built godlike technology while running on Paleolithic instincts. Upgrading the mind that wields the tools is starting to look less like ambition and more like duty.

Governing AI from the First Brain: How to Regulate AI

Regulating AI faces two traps: law moves slower than tech, and you can't write rules for what you don't understand. The deepest lever is upgrading the regulators.

High-Context Minds in a Low-Context AI World

AI gives better output with better context because a model is low-context: it knows only what you type. Giving it good context starts with a clearly mapped mind.

How to Use Obsidian to Upgrade Your First Brain

Obsidian is a mirror: it reflects your mind, it does not create it. To use it for thinking, link on capture, write atomic notes, and review by retrieval, not features.

Do Hyperbaric Chambers Improve Intelligence?

Do hyperbaric chambers improve intelligence? Not exactly. HBOT can improve specific cognitive functions via angiogenesis, but it upgrades hardware, not knowledge.

Are Mind Maps Better Than Notes?

Are mind maps better than notes? For recall, often yes. A radial map matches the brain's associative wiring; a linear list fights it. Here is the evidence.

Obsidian vs. The First Brain: Is It a True Second Brain?
