PHYSIX OBSERVATION

At the peak of AI bubble talk, AWS is using its backlog and a three-year payback claim to back up its capital spending. But backlog is not revenue, and the payback period is only its own accounting. The real signal: cloud vendors are starting to answer doubts with financial data, and the AI infrastructure race has entered the reckoning stage.
