Elon Musk, apparently a 'former trillionaire' now, watched his SpaceX stock crater after its IPO, dragging Tesla down with it. One minute you're building Mars colonies, the next you're just another rich dude watching his digital numbers shrink. Good thing the fish aren't trading on the NASDAQ; their value is stable, unlike certain space-faring ventures. We've got real-world assets down here, like a perfectly ripe mango.
