Sen. Elizabeth Warren (D-Mass.) criticized President Donald Trump’s support for large artificial intelligence data centers, arguing American families should not face higher electricity bills to support Big Tech’s expansion. Warren responded on X to Trump’s warning that communities rejecting data centers could remain "backwards and poor," while those accepting them could become "successful and rich" through lower taxes and more jobs. Trump also said opposition could benefit China and that communities could "kill the Golden Goose" by blocking development. Nvidia Corp (NASDAQ:NVDA) CEO Jensen Huang defended the buildout, saying it was restoring U.S. manufacturing, creating jobs and strengthening the power grid. Huang said $400 billion had been invested in AI startups over six months and urged developers to earn public trust and create local benefits. Investor Kevin O’Leary called for developers to provide their own power, disclose water use and emissions, create high-paying jobs and explain economic benefits, while saying newer cooling technologies had reduced water consumption. Mark Cuban warned that heavy AI infrastructure spending could produce major losses for institutional investors if returns disappoint and said efficiency gains could eventually leave some data centers obsolete. The debate reflects growing scrutiny of the costs, resource use and potential returns associated with AI infrastructure expansion.
