Why America’s debt binge is starting to matter
Interest rates above 5% could freeze AI capex. Here's why the debt cycle matters to your compute budget.

Why it matters
US debt and interest rates are a macro constraint on AI infrastructure spending. If long-term rates spike, the massive capex buildout funding frontier compute gets starved — affecting chip orders, data-center deployment timelines, and which labs can afford to scale.
The key facts
4 to knowLong-term interest rates as a threshold mechanism for AI capex (5% breach cited as critical)
Debt-driven rate environment as infrastructure financing constraint
Implicit connection: AI boom depends on cheap capital for compute buildout
Macro risk to the chip/data-center expansion cycle
