The one-plot summary of what Elon Musk did to Twitter.
This is where it gets wild 👇
In 2020, Twitter use was highest among people who loved Democrats and disliked Republicans.
By 2024, it completely flipped: the more polarized Republican you are, the more you use Twitter/X.
From blue stronghold → red megaphone. All for just $44 billion.

This is a poor argument against LLM simulations. It suggests that LLM-based behavioral models should capture nuances that no model ever has (do agent-based models go to the toilet?). Ofc, ABM is meant to be interpretable, but social science also needs predictive power (where LLM simulations excel)
1. A large and growing literature on "generative agent-based modeling" aims to study social science questions by using LLMs to simulate the behavior of people in naturalistic situations.
I think it's a lost cause, for the same reason I was sent to the principal's office in third grade.
