Pydantic creator samuelcolvin quote-shared an article titled "The code IS the graph," laying out his full critique of graph libraries.
Key points:
- Graph libraries are a design mistake; your code already is the graph;
- Code gives you type safety from type hints, parallel execution from async, and durable execution via Temporal outside the sandbox;
- The author says this is his first proper write-up of long-held criticisms, framed as "Graphs are dead, long live graphs."
