About

Hathaway Field Notes is a systems-level look at technology and the world.

This is the external brain of an engineer who sees the world as a product — analyzing how humans interact with and benefit from technology through a logical, methodical systems-thinking lens.

What you'll find here

• Observations — Short-form thoughts. A product behavior or friction point spotted in the wild.
• Artifacts — Curated links, references, and breakdowns with context on why they matter.
• Signals — Long-form essays that synthesize observations into predictive frameworks. Signal out of the noise.

The lens

Every piece of technology creates a feedback loop with its users. These notes deconstruct those loops — identifying bottlenecks, friction points, and the incentives that drive the system. If the tech doesn't improve the human system, it isn't working.
