Lax information hygiene norms beg memetic attacks

9/11 was caused by lax controls in freedom of movement for people. Consonant with Herbert Schiller’s critique of freedom of information, a memetic equivalent of the 9/11 might occur in the future, due to the lax norms of information hygiene. Malicious memes can easily propagate in the global information society. This could be an unfortunate side-effect of capability development in the space of memetic psychotherapy. This hypothetical event closely resembles the “Meltdown” from one of Greg Egan’s short stories.
