Reuters examines AI's investment-return race as long-run data-center spending could reach $30T and productivity gains remain the key test

What changed

Reuters published an October 3 analysis of the extraordinary scale of global AI infrastructure investment and the revenue and productivity gains ultimately needed to support it. The report cites a PwC projection that cumulative global data-center spending could exceed $30 trillion by 2050 and examines long-term compute commitments, hyperscaler capital expenditure and economists' skepticism about how quickly broad productivity gains will arrive. This is an industry-economics analysis rather than a new model or product launch.
