How would this make sense if the market is a bubble? Bubbles pop by definition and you end up losing everything? Not sure what it has to do with your employment.
"Lose everything" is a wild stretch. They have 30% in a moderately broad fund. They have a chunk in companies that are still doing non-ai things, then their first part is chip manufacturers. AI could disappear and people would still need computers.
I imagine a world where anyone has an AI powerful enough to make apps that used to require a full team of professional software developers and do so much quicker. If we get to that world, I don't see how the stock market wouldn't be significantly higher than today, even if it's in a bubble today.
