🧭 Welcome back to The Sextant™
The Sextant™ is a recurring series of board-level briefings on the hidden constraints shaping the infrastructure in deep-tech. Each issue isolates one constraint and ends with the questions a director should carry into the next board meeting.
1️⃣ Executive Summary
Four weeks ago this series named the first hidden constraint: packaging, not silicon. Two weeks ago we named the second: substrate selection, a five-to-twelve-year capital commitment. Today we name the third, one layer above silicon and the foundation model: the person qualified to negotiate at the substrate layer. Inference and physical AI converge on one question: who in your organization holds the credential, the standards-body fluency, and the carrier-grade discipline to make a substrate decision that compounds across product cycles?
