      This year companies will spend $400bn on the infrastructure needed to run artificial-intelligence (AI) models. Predictions of the eventual bill are uniformly enormous. Analysts at Morgan Stanley reckon $2.9trn will be spent on data centres and related infrastructure by the end of 2028; consultants at McKinsey put it at $6.7trn by 2030. Like a bad party at a good restaurant, nobody is quite sure who will pick up the tab.
