## Nauti's Take

This does not prove the AI boom is over. It is more like the first serious stress test for a story that has framed almost every cost as an investment in the future. If data centers, chips and models keep being financed with debt, markets will eventually demand visible cash flows. PR will not be enough, even if the technology itself remains real.
