* Major terrorist attack in israel; its obvious we care way too much about this random country on the other side of the planet but even so i can't see that impacting people's happiness this hard.
* general populace now knows LLMs exist and may someday potentially perform jobs which were previously thought to be immune to automation but i would expect this to be offset by the people amazed by this technology.
* It's becoming increasingly apparent that our then-current president might actually suffer from a more serious case of Alzheimer's than reagan did; simultaneously it is becoming increasingly apparent that the only viable alternative is going to be trump again.
#3 is the only one that sort-of makes sense but I have doubts that people are this invested in presidential circuses on a personal level.
