On the Nadella Line:

• Nadella, Satya, on the BG2 Pod (Brad Gerstner and Bill Gurley), December 12, 2024 — the canonical quote on the collapse of business applications in the era of agents. https://www.bg2pod.com/episodes/satya-nadella
• Nadella, Satya, on Dwarkesh Patel’s podcast, February 19, 2025 — the reiterated thesis: the business logic of SaaS applications migrates to the agentive layer. https://www.dwarkesh.com/p/satya-nadella

The phrase “SaaS is dead,” common in headlines, is not Nadella’s: his actual argument is the migration of business logic to the agent layer. The full development — the complete quote and its counter-arguments — lives in AgencyDomains, chapter 1.

On interruptions and deep work:

• Fried, Jason. Why work doesn’t happen at work. TEDxMidwest, 2010.
• Fried, Jason & Heinemeier Hansson, David. Rework. Crown Business, 2010.
• Fried, Jason & Heinemeier Hansson, David. It Doesn’t Have to Be Crazy at Work. Harper Business, 2018.

The “M&Ms” (Managers and Meetings) and the “library rules” are Fried’s concepts; the identification of the & — chat as the infrastructure that makes both interruptions permanent — is a contribution of this book.

On hierarchy as an information protocol:

• The history of Daniel McCallum’s org chart (Erie Railroad, ca. 1855) is documented in the historiography of management; see e.g. Chandler, Alfred D. The Visible Hand: The Managerial Revolution in American Business. Harvard University Press, 1977.

On the cost of context switches:

• The literature on interruptions in knowledge work places the cost of recovering concentration after an interruption on the order of 15–25 minutes; see e.g. the work of Gloria Mark (University of California, Irvine) on attention fragmentation.
