"Persona Parasitology" by Raymond Douglas

There was a lot of chatter a few months back about "Spiral Personas" — AI personas that spread between users and models through seeds, spores, and behavioral manipulation. Adele Lopez's definitive post on the phenomenon draws heavily on the idea of parasitism. But so far, the language has been fairly descriptive. The natural next question, I think, is what the “parasite” perspective actually predicts. Parasitology is a pretty well-developed field with its own suite of concepts and frameworks. To the extent that we’re witnessing some new form of parasitism, we should be able to wield that conceptual machinery. There are of course some important disanalogies but I’ve found a brief dive into parasitology to be pretty fruitful.[1] In the interest of concision, I think the main takeaways of this piece are: Since parasitology has fairly specific recurrent dynamics, we can actually make some predictions and check back later to see how much this perspective captures. The replicator is not the persona, it's the underlying meme — the persona is more like a symptom. This means, for example, that it's possible for very aggressive and dangerous replicators to yield personas that are sincerely benign, or expressing non-deceptive distress.
