OpenAI's push for a government guarantee behind AI spending is being read as a warning sign — bad news for taxpayers, and a sign the AI boom may be shakier than it looks.

• OpenAI's leadership has floated the idea of a government "backstop" and Sam Altman has said Washington should be the insurer of last resort for AI.
• Asking for a safety net before anything breaks suggests the company already expects trouble.
• Banks have borrowed heavily to fund AI buildouts, so a bust would hit the financial system, not just tech.
• A bailout would land on taxpayers already carrying $40 trillion in national debt.
• Public anger would be far harder to contain than in 2008, with online media making it obvious who got rescued.

Outlook: If the AI bubble pops, expect a fight over whether Washington rescues the banks and AI firms again — and a much angrier public than last time.
