chatGPT on anti-memetic shields:

Designing anti-memetic shields is a conceptual exercise grounded in information theory, cognitive science, and security models, with speculative applications in fiction, advanced AI, and possibly future cognitive environments. Here’s how to approach it from first principles.

Goal of an anti-memetic shield

Prevent a meme (or meme-like cognitive infection) from:
•Entering a mind or cognitive system.
•Being stored or recalled.
•Being transmitted to others.

This is analogous to firewalls, antiviruses, or quarantine systems for ideas.
