Field notes from the First Brain.

What Cannot Be Replaced by AI? Unprecedented Synthesis
What cannot be replaced by AI? The synthesis of the genuinely new. AI interpolates between what it has seen; a First Brain leaps into dimensions the data never had.
Video Calls, Holograms, and Low-Bandwidth Telepathy
Will video calls be replaced by holograms? Yes, but holograms upgrade the messenger, not the message. The real endgame is brain-to-brain bandwidth.
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.
How to Build an Exocortex That Matches Your Brain
What is an exocortex and how do you build one that matches your brain? Mirror your mind's own graph, not a folder tree. Here is the practical method.
Are AI Tutors Good for Kids? The Cognitive Cost
Are AI tutors good for kids? Only if they withhold answers. A tutor that hands over solutions can leave a child measurably worse off once it is removed.
What Comes After Human? Map the Mind First
What comes after human? Enhanced humans, uploaded minds, a merger with AI. Every path shares one prerequisite: a mind you have mapped well enough to carry forward.
The Best Note-Taking App for ADHD (and Why Notion Isn't It)
The best note-taking app for ADHD is the one with the least friction and structure to maintain, which is almost never Notion. The mismatch is structural.
The Limitations of Language: A 1D Channel for a Graph
What are the limitations of language? It is linear, ambiguous, partly ineffable. It forces a multidimensional thought into a one-dimensional line, losing much.
Best Enterprise AI Search? Why Your AI Wiki Failed
The best enterprise AI search barely depends on the tool. Most fail for one reason: you indexed the manuals, the leaf nodes, not the experts' root intuition.
Will Neuralink and BCIs Replace the Keyboard?
Will Neuralink and BCIs replace typing? For the paralyzed, BCIs already hit 90 characters a minute. For everyone else it is far off, and speed is not the real limit.
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.
The Best Exercise for Brain Health Is Zone 2 Cardio
The best exercise for brain health is aerobic cardio, and Zone 2 is the underrated sweet spot: it grows the brain and is the rare workout you can think during.
How to Use AutoGPT for Research: Bring a Blueprint
How to use AutoGPT for research? Only on topics you already understand. Agents hallucinate mid-task, so you can only delegate what your First Brain can verify.
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.
How the Autistic Brain Organizes Information
How does the autistic brain organize information? By hyper-systemizing: a strong drive to find the exact rules and patterns in a system, building precise structure.
Can a Brain Chip Be Hacked? Build a Mental Firewall
Can a brain chip be hacked? In principle yes, researchers call it brainjacking. The one store no attacker can reach is knowledge held natively in your head.
BCI Implants for the Elite: What Neuralink Really Costs
Reported Neuralink prices start around 10,000 dollars, but cost is the wrong number to watch. A brain chip only amplifies the mind you plug into it.
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.
