Tesla Inc. CEO Elon Musk on Monday slammed New York City Mayor Zohran Mamdani's plan to run city-owned grocery stores across the Big Apple's five boroughs, reaffirming his prediction that robots and artificial intelligence will provide free goods and services. In a post on X, All-In Podcast host Jason Calacanis shared a video of Mamdani saying that NYC will issue a Request for Proposal to select individuals or businesses to operate the city-owned grocery stores. Calacanis said the selections would be based on the principles of Diversity, Equity, and Inclusion, and that Costco Wholesale Corp already had "Zero Profit Margin" groceries. Musk responded, saying "What they're doing won't matter," adding that "AI & robots will actually deliver the free goods & services that those thieves pretend to offer," and calling Mamdani a "thief and a liar." The New York City Mayor's Office did not immediately respond to Benzinga's Request for Comment. Responding to a separate post, Musk accused Mamdani of wanting "a propaganda tool to undermine the free market." Musk has touted AI and robots as capable of delivering goods and services, saying productivity would surge and that governments would provide for people because AI productivity would increase to an extent that Earth would "actually run out of things to do for the humans." Critics remain skeptical; Sen. Bernie Sanders recently asked Musk to back a wealth tax if he believed "money won't matter" by
