the economy and stock market taking a huge hit
Two things that have also failed to manifest, in large part thanks to the prolific state spending following COVID.
Keep in mind, the event that really knocked over the tower of cards in 2008 was Greenspan's decision to raise interest rates (very sharply) in 2007. Trump's very obviously not going to do that. If anything, he's been working overtime to get interest rates lower, because he knows cheap money = high (raw) GDP growth and low unemployment.
What we're seeing isn't recessionary. It's a glacial shift in the economic priorities of the US, from a post-Reagan titanic banking juggernaut to a post-COVID more-WW2-style global arms depot. The US economy increasingly makes cops and bombs and machines that assist cops and bombs. And there's no recognized upper limit for demand on these goods and services. Not under current geopolitical conditions, anyway.
Data centers in Silicon Valley stand empty, awaiting power
One of the more curious artifacts of the recent surge in data center construction has been filling these megaliths with hardware and then... not plugging them in. Either because turning them on would flatten the local electrical grid or because they're loss-leaders for which data cycles only cost the company money.
So you've got this multi-billion dollar paper asset that wows investors while it gathers dust. And then you go off to build another one, because people will fling their unlimited borrowing power at you to reap another quarter of double-digit growth in speculative valuation.
