Former AI czar calls Sanders' proposal for government equity a 'stupidity tax' and warns against nationalization as Trump mulls public stakes

David Sacks calls Sen Bernie Sanders' proposal for 50% federal ownership of AI companies a 'stupidity tax' and warns against government nationalization. Sacks argues AI CEOs have exaggerated risks without showing benefits. The criticism comes as OpenAI and Anthropic CEOs shift from AI apocalypse warnings to focusing on upcoming IPOs. Sacks acknowledges the proposal has appeal among conservatives despite his opposition.
