Likewise, LLM's won't disappear completely with a stock market crash. But the weaker players might.

Yes, so the theater piece and the actors get all the fame and money, but are more likely to be deemed irrelevant and passé by tomorrow morning, but the building and the cleaning person are more likely there to stay for quite some time.
