Obsidian knowledge vault — viral 'Anthropic engineer brain' graph
50k ft — Why care?
Viral claim that an Anthropic engineer's Obsidian vault (~8,900 nodes) is structured like a neural network and runs internal decisions. Unverified hype, but the underlying point is that disciplined markdown linking in Obsidian scales into a real knowledge graph.

Anthropic’s lead engineer accidentally leaked his personal Obsidian vault.
Inside: no code, no prompts. Just a schematic of his own mind, built like a neural network.
8,893 nodes. 4,729 links. A $10-a-month app
opens Obsidian. 21 inputs, 10+ hidden layers, ReLU activation. First layer 64 neurons, then 37, then 22, all the way to the output. Thousands of connections firing in real time
this isn't a concept diagram from a blog - it's a living brain that actually runs decisions inside the company. 9,000 documents, each its own knowledge space, all interconnected
he makes around $2M a year for putting markdown files into the right folders. The company building the best AI in the world manages its internal knowledge with the same app a college freshman uses for lecture notes.
