The layers of the stack don't move. Regulation doesn't retreat, encoded knowledge doesn't decay, first-party data keeps compounding. What moves is everything outside them — how much AI can already do without you, and therefore how many of your customers still have to buy.
So picture your market as a pyramid. The most demanding customers sit at the narrow top; the least demanding at the wide base. Now draw a waterline across it. Below the line, the customer can have AI build it outright — or AI absorbs the job entirely. Above it, the complexity still justifies buying.
The line is not fixed. AI lifts it. And as it rises, your layers don't weaken — the set of customers they protect shrinks from the bottom.
“The stack gives you altitude. The waterline gives you rate. You need both to answer the only question an owner actually has: how many years are left, and which layer goes first.”
Chegg's customers sat at the base of its own pyramid: students with routine questions, the widest and least demanding layer in that market. The waterline didn't cut through Chegg's category. It rose past the whole thing in one step.
Quentic's customers sat near the top: industrial operators tracking incidents and audits across multiple sites and jurisdictions, where being wrong means fines, shutdowns, or someone getting hurt. Well clear of the line. Same four layers, same rising water, opposite outcome.
