The Repriced Engineer
As the industry shifts from rule-based to token-based delivery, the capability bundle of software engineers is being repriced: raw coding depreciates while judgment becomes the new scarce asset.
Read article [READ] →From API Gateway to AI Gateway: When Infrastructure Is Stretched by Tokens
LLM traffic breaks the two hidden assumptions of the traditional API gateway — opaque payloads and deterministic behavior — and forces a new infrastructure layer that governs non-deterministic calls.
Read article [READ] →Software Ate Only Half the World: From Rule-Based to Token-Based
A long-form reflection on why software has only ever eaten the rule-codifiable half of the world, and how tokens are opening a second industrial track for the other half.
