It runs on physical machines, in physical buildings, drawing very physical electricity, built from very scarce materials. And in 2026 those physical limits are starting to push back — on the power grid, on chip supply, and soon, on the price of the phone in your pocket. The buildout nobody can see The visible face of AI is a chat box. The invisible half is a global construction boom. To train and serve today's models, companies are racing to build data centers packed with specialized chips that run hot, hungry, and around the clock. This year the strain became impossible to ignore: Google reported that its data centers helped drive a record 37% jump in its electricity use , and Meta began renting out its own AI compute to keep the economics working. The demand for processing powe...
