Big Tech is pouring hundreds of billions into AI data centers that can't even get plugged into the power grid, and cracks in the financial story behind it are starting to show — bad news for investors, retirees, and anyone whose 401(k) touches tech stocks.

• Power grids can't keep up: wait times to connect new data centers have stretched to 7-12 years in some regions, leaving billions of dollars of chips sitting idle and losing value fast.
• Companies keep spending anyway out of fear of falling behind rivals, and Wall Street is punishing them for it — Meta and Microsoft each lost hundreds of billions in stock value in a single day after revealing massive AI spending.
• Investor Michael Burry, who famously called the 2008 housing crash, says companies like Microsoft, Meta, and Amazon are using accounting tricks to hide huge costs and inflate profits, similar to tactics used in the WorldCom fraud of the early 2000s.
• Much of the debt funding this boom is being pushed into insurance funds, pensions, and 401(k)s, meaning ordinary workers and retirees are increasingly exposed if the bubble bursts.
• The surging power demand from data centers is already raising electricity bills for regular households and straining grids in places like Texas and Virginia.

Outlook: Expect more financial strain and possible shakeouts among weaker AI players as spending collides with grid limits and investor doubts, with risk increasingly spilling over into ordinary people's retirement savings.
