Yes. SpaceX had their IPO and retirement accounts automatically bought the stock, according to their formulas. So the last thing regular people need is for these AI companies to do their IPO's and have 401Ks starting buying them. Then they'll cash out and leave everyone else holding the bag.
But even if they never go on the stock market, so many other stocks are tied to what happens to them that if they crash they'll bring them down too. Especially Nvidia, but also lots of chip manufacturers and all kinds of other businesses related to hardware, data center construction, etc. Right now they're making tons of profit from the spending of all that borrowed money and some of them, like Nvidia, are investing right back into the AI companies. It's a house of cards that's going to screw us all. 2008 will seem like a minor blip by comparison. 😭
