Former Greek finance minister Yanis Varoufakis argues that capitalism has ended, giving way to 'techno-feudalism' where big tech companies control human behavior. He warns of the risks posed by stablecoins and the privatization of the dollar under Donald Trump, suggesting this could lead to a financial crisis similar to 2008. Varoufakis emphasizes the need to democratize central banks to rebalance economic power and make money a commons rather than a privilege.
