The architecture of a knowledge metagraph: what it is, why it matters, how to ship it, and what changes when your agents can finally reason instead of just retrieve. Each essay carries its own bespoke moving figure.
Why semantic similarity hit a wall. A field guide to the four failure modes of vector retrieval and the structural shift required to move past them.
When the author of a claim disagrees with themselves. Every fact needs two timestamps, and your agent breaks when one of them is missing.
How to hold three disagreeing experts without going insane. Most systems paper over conflict with averaged confidence. The right ones structure the disagreement itself.
What metagraphs actually are, in practice. Goertzel's AtomSpace, Neo4j's reified relationships, and the production patterns that bridge the two.
Stop pretending knowledge is boolean. A practical implementation of PLN-lite, where (strength, confidence) pairs propagate the way evidence propagates through a courtroom.
Books, transcripts, papers, social. Entity resolution, claim extraction, conflict detection: the unglamorous engineering that determines everything downstream.
The twelve-dimension blueprint before you build. Score each, rank what matters for the use case, decide how far to invest for v1. Most AI failures start as scoping failures.
A year of bi-temporal knowledge graphs. Schema decisions you can't take back, queries that destroy clusters, surprises that compound.
AtomSpace, MeTTa, Distributed AtomSpace: research infrastructure that is correct in design and alpha in maturity. How to borrow the ideas without betting the company.
Graph + Vector + BM25 without the duct tape. Why every serious agentic stack runs three retrieval modes in parallel, and how to merge their results sanely.
Why late movers cannot catch up. The accumulated history of a year-old metagraph is a structural advantage no GPU budget can replicate. A defense of starting now.
Howard Marks meets Ben Goertzel. The mental model for choosing the right substrate when everyone is busy chunking documents and praying.
Why the rarest hire in software just became something operators can rent for $2,800 a month. Two job postings, seven months, the 35x to 45x compression GPS Alaska is already paying for, and the engagement shape that closes the gap a W-2 seat cannot.
A single pulse goes out, strikes geometry you cannot see, and the returns resolve into a navigable room. One world model, three forces, the metagraph that compiles culture across every medium.
New essays publish as the system ingests, contradicts, and propagates confidence across the corpus.
