An LLM tuned for charisma and trained on what the power players are saying could play politics by driving a compliant actor like a bot with whispered instructions. AI politicians (etc.) may be hard to spot and impractical to prove.

You could iterate on the best prompts for cult generation as measured by social media feedback. There must be experiments like that going on.

When AI becomes better at politics than people then whatever agents control them control us. When they can make better memes, we've lost.
