The Constraint Above the Chip
After packaging, substrate, and memory clear, the binding scarcity is energized power, and time-to-power is the layer that prices everything above it.

🧭 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 issues walked this series down into the chip:
Capacity first,
Then substrate selection as a five-to-twelve-year commitment,
Then the qualified individual who negotiates at that layer,
Then the packaging, ABF substrate, and memory chokepoint that gates every accelerator.
Today the series turns the other way, up and out, to the layer that decides whether any of that silicon ever runs: electrical power, and the time it takes to energize it.
Inference, training, and physical AI converge on one question: do you own your time-to-power, or does someone else price it for you?
