Just how much power will AI need?
Agentic AI could redraw the compute map: data centers aren't ready for the power demands ahead.

Why it matters
As AI shifts from inference to multi-step autonomous reasoning, power consumption per workload will spike — forcing a reckoning on data-center capacity, cooling, and grid infrastructure that practitioners and operators need to plan for now.
