How to Become a 10x Engineer: Just Be a Graph Thinker

The 10x developer doesn't type faster. They hold the whole system as a mental graph, write less code, and catch bugs others miss. It's architecture, not speed.

How to Focus for 4 Hours: The Deep Work Marathon

You can't focus 4 hours unbroken, and you shouldn't try. Even elite performers cap at 3-4 hours of deep work a day, run in 90-minute blocks. Build it like a runner.

Will AI Replace Doctors? The AI Doctor's Blind Spot

AI can match doctors on textbook diagnosis, yet it has a blind spot: the unspoken context of the patient in the room. That context is a human First Brain's job.

Why Is AI Making My Team Slower? The Productivity Paradox

AI made it trivial to generate documents, so teams drown in low-value workslop. The bottleneck moved from making content to the human work of synthesizing it.

How Do Architects Think? The Mind That Holds 3D Volumes

Architects don't think in floorplans. They build navigable 3D volumes in the mind and walk through them. That spatial habit is a blueprint for a First Brain.

How to Annotate a Book Properly: The Art of the Marginalia

Stop highlighting, one of the least effective study habits. Write marginalia instead: questions, objections, links to other ideas. Active marginalia is what sticks.

AI for Enterprise Knowledge: The Corporate Exocortex

Generic AI gives generic answers about your company. A corporate exocortex grounds the model in your own knowledge graph, but tacit culture still needs humans.

Can a BCI Read Intrusive Thoughts? Accidental Execution

Today's BCIs read attempted action, not your whole inner monologue. But inner speech does leave a trace, which is why separating idle thought from intent matters.

Why Can't I Read Books Anymore? The Death of Deep Reading

You can't read books anymore because your brain forgot how to hold an idea in working memory long enough to connect it. The good news: the circuit is rebuildable.

Will Voice AI Replace Typing? The Keyboard's Death

Speaking is about three times faster than typing, so voice AI is taking over capture. But voice is a linear stream, and structuring it is still your job.

How to Enjoy Hard Work: The Dopamine Baseline of a Genius

Hard work feels boring because cheap dopamine raised your baseline. Lower it, reward effort over results, and the click of two ideas connecting becomes its own high.

Does Dual N-Back Actually Work? The N-Back Illusion

Dual n-back makes you better at dual n-back, and little else. The famous IQ gains failed to replicate. Structure, not a memory game, is the real upgrade.

Are Exams Unfair to Neurodivergent Minds? The End of Tests

Standardized tests measure linear recall under time pressure, which penalizes divergent minds. As value shifts to synthesis, the test that favors them is ending.

How to Curate High-Quality Info: The Farm-to-Table Diet

AI-summarized newsletters strip out nuance and add errors. Go farm-to-table: read the primary source yourself and map it natively. Slower, but it sticks.
