Notes: AI Bubble? Spending, Risks, and Returns — A High-Level Assessment

Summary * Hyperscalers’ AI capex is soaring past historical limits, forcing creative financing and intensifying scrutiny over ROI and long-term sustainability. * Despite fears of an AI bubble, utilization remains high, demand is outpacing capex, and efficiency breakthroughs from Chinese labs are lowering compute costs while expanding practical use cases. * The
