# Jack Dorsey

## Profile

Jack Dorsey is the co-founder and CEO of [[entity-block]] (formerly Square) and is referenced in this source as a primary example of a leader attempting to build a [[concept-world-model]] based on the [[concept-signal-fidelity]] architecture.

## Role in This Source

Dorsey recently published a blueprint for the World Model concept that gained massive traction (cited as 5 million views in 2 days). His core thesis at Block is that **'money is honest'** — meaning that financial transactions provide a pristine, undeniable data exhaust that is far superior to text-based communication for feeding an AI model.

By building a World Model around this high-fidelity signal, Dorsey aims to create a highly accurate, automated system for understanding the reality of the business.

## Canonical Quote

See [[quote-money-is-honest]] — paraphrased by [[entity-nate-b-jones]] from Dorsey's published blueprint.

## Why He's a Cautionary Example

While Dorsey's architecture is the most pristine of the three (see [[framework-world-model-architectures]]), this very pristineness is a danger: it produces the [[claim-illusion-of-judgment]] — pristine inputs make causal interpretations *feel* authoritative even when their reasoning is thin.
