Part I
The Argument
The reader learns why the discipline must exist.
A founding textbook
Your company bought AI the way it bought software: a seat, a price, a yearly contract. But AI is not software. It is a utility that requires resource consumption. Every usage requires compute. More questions mean more compute. Harder tasks require more compute. Start managing AI for what it actually is, not how it is priced today.

The formal spine
Every argument in this book traces to a registry of theorems, lemmas and propositions. The registry justifies the book; it does not organize it. This is the anchor of Chapter 1, reproduced exactly as the chapter sets it.
Theorem 1 · THM-009
AI Use Is Resource Consumption, Not Merely Software Access
Within a defined deployment and cost boundary, if:
then that AI use is a resource-consuming operating activity, not merely software access.
A theorem here applies only when its stated conditions hold. That is what makes it usable, and what makes it falsifiable.
Method
That rule is easy to state and expensive to keep. Here is one paragraph from Chapter 1 exactly as it is published, with the note it carries and the register entry that produced the note. This is the reading experience and the sourcing apparatus, unedited.
As published
On July 4, less than three weeks after the change, Michael Truell apologized and promised refunds for charges incurred during the transition. Truell is chief executive of Anysphere, the company behind Cursor. His explanation reduced the dispute to arithmetic. The newest models consumed far more tokens on long-horizon tasks than a flat monthly price could cover.11 Michael Truell, “Clarifying Our Pricing,” Cursor, July 4, 2025, accessed July 29, 2026; Maxwell Zeff, “Cursor Apologizes for Unclear Pricing Changes That Upset Users,” TechCrunch, July 7, 2025, accessed July 29, 2026. The Cursor post describes the change of June 16 and the clarification of June 30. The TechCrunch report carries Truell’s role and title.

Behind this entry the register also holds an editorial note: what the source does and does not support, which sentences it licenses, and the condition that would reverse each ruling. That note is the working record of the fact checks and stays unpublished, but it is the reason the sentence beside it reads exactly as it does.
