GDP growth in the United States is in AI and healthcare. AI capital expenditure is around 5% of total US GDP. Housing right before the 2009 market collapse was around 6.7%.

Biggest issue I see is housing has more real value than AI expenditure. Demand is real and isn't based purely on a few companies valuation or marketing spin. Nearly 2 decades later we still haven't caught up to construction rates before the 2008 collapse. When the bubble pops it's going to really suck.
