What Makes a Good Backlink? The Same Rules for Your Mind
What makes a good backlink? Relevance, authority, and natural placement. The same three rules decide what makes a good link inside your own mind.
What Happens at a 10-Day Silent Retreat? Defragging
What happens at a 10-day silent retreat? Not peaceful emptiness. With no input, the mind surfaces and processes its backlog, a brutal defragmentation.
Zettelkasten vs. Mind Maps: The Cognitive Differences
Zettelkasten vs mind mapping is not linear vs graph. Both are graphs. The real differences are timescale, depth, and whether either makes you smarter.
AI as a Second Brain: Why You Need a First Brain First
You can use AI as a second brain, but it amplifies what is there. Garbage in, garbage out: build the First Brain first, then let AI amplify real understanding.
Are People Buying Custom AI Models? The Black Market
Are people buying custom AI models? Yes, a black market sells tuned, guardrail-free ones. As base models commoditize, the scarce asset is a real First Brain.
Analysis Paralysis in the Second Brain: Why You Can't Organize
Can't organize your life? Digital systems cause paralysis: infinite options plus no intuition for where things go. The fix is a clearer First Brain, not a better app.
Best Local-First Note App? Own Your Exocortex
Best local-first note app? One where you own the data, it works offline, and no server gatekeeps it, like Anytype. The right external exocortex, not the first.
Why Create Art If AI Makes It Faster?
Why create art if AI makes it faster? Because making art physically remodels your brain. AI hands you the image and skips the neural change that was the point.
Audio-Node Mapping: Run a Business on Your Phone
Running a business on a phone alone? Hold the real map in your head, and use voice notes only as a fast, temporary cache. The mind is the system, not the device.
Before the Machine Saves You: A Word on Human Enhancement
The honest final word on human enhancement: no app, chip, or AI can save a mind that has gone to sleep. Build your First Brain before you reach for the machine.
Do Binaural Beats Work for Studying? The Evidence
Do binaural beats work for studying? The evidence is mixed and modest, and the entrainment claim is unproven. At best they set a focus state, not the learning.
Can Wearables Track Mental Fatigue? Gauge vs Upgrade
Can wearables track mental fatigue? Indirectly yes, HRV and pupil signals flag the load. But the gauge only shows the RAM is full. The First Brain adds RAM.
Best Biohacks for Mental Clarity? Hack the Software
Best biohacks for mental clarity? Cold plunges and nootropics tune the hardware and work. But a sharp brain running no real thinking is a fast machine idling.
Black Swans and Biological Imagination
You cannot predict a Black Swan; by definition it is outside the data. AI is worse at it than you. The human edge is imagining the impossible and building to survive it.
Building an Off-World Second Brain for a Space Colony
How to build a database for a space colony: design for total isolation. With Earth minutes away, it must be offline-first, redundant, and shaped to how the crew thinks.
Object-Based Note-Taking: Why Objects Beat Pages
Object-based note-taking treats every note as a typed thing, a person, a book, an idea, instead of a page in a folder. It mirrors how your First Brain already works.
Data Privacy and the Exocortex: Feeding AI Your Notes
Is it safe to feed your second brain to AI? Consumer AI often trains on your inputs by default. Reduce the risk, but keep your most private thinking in your First Brain.
Can We Survive Without Computers? The 20-Watt Brain
Can humanity survive without computers? Yes, the original one runs on 20 watts of glucose and oxygen, not a power grid. The First Brain is the resilient substrate.
Why You're Addicted to Organizing Your Notes
Why am I addicted to organizing notes? Rearranging the vault is productive procrastination: a cheap dopamine hit. Real learning pays out after friction.
How Do I Know If My Notes Are True? Build a Verifier
How do I know if my notes are true? Not in isolation. A claim is justified by how it coheres with your wider web of knowledge, so you need a built mind to check it.
The Local-First Exocortex: Run a Private LLM on Your Notes
You can run a private LLM over your own notes, fully offline. But RAG only reflects what you wrote, so the answers are capped by how well-structured your notes are.
The Future Entrepreneur: From Operator to Philosopher
Future of the entrepreneur? As AI drives execution to near-zero cost, the founder shifts from managing operations to supplying vision, taste, and judgment.
What Replaces Notion and Obsidian? Generative UI
What will replace Notion and Obsidian? Not an app, but generative UI: interfaces built on the fly by AI. When the app dissolves, your First Brain steers.
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.
