The agentic expansion theory — sandbox → tool use → computer use → convergence — is usually read as a product roadmap. Each lab ships the next phase; each phase looks like a feature release.
The structural reading is different. The expansion is not a product decision. It is the substrate requirement of the scaling law that now defines AI progress. Once that is seen, the cascade across the rest of the AI map is not a forecast — it is a settlement.
This piece has two parts. Part I explains why the expansion is happening, from the AI scaling perspective. Part II runs the cascade forward across the seven layers of the AI map that result in a reprice.
The standard narrative treats AI scaling as a sequence. Pre-training was 2022–2023. Post-training was 2023–2024. Test-time compute was 2024–2025. Agentic loops are 2025–2026. Each paradigm “replaced” the last. That framing is wrong in a way that matters for capital allocation and productstrategy.
