A 60-year investing veteran who once managed $165 billion says US stocks, tech, crypto, and SpaceX are all dangerous bets right now — bad news for almost anyone with savings in the market.

• The advice is blunt: don't own US stocks, including the S&P 500, and sell any big US tech holdings.
• AI is called the biggest investment bubble ever, bigger than railroads or the internet.
• Bubbles always form around world-changing ideas, people pile in, overinvest, and then the crash brings years of economic pain.
• Bitcoin and crypto are dismissed as useless and predicted to go to zero, with SpaceX waved off as an overhyped story.
• The bigger the bubble, the bigger the bust — and this one is expected to break within the next few years.

Outlook: A painful market crash and tough economic stretch are seen as likely once the AI bubble pops, possibly within months but near-certain within a few years.
