There's another fun biology metaphor here which is the gut.

If you take antibiotics, your gut basically becomes a void (to simplify a little), and then it can get overrun with invasive species.

That's how I see what is happening with the internet and with AI.

When AI intrudes in a network, it's able to get very far because there is nothing there to stop it. There is no healthy ecosystem there. They're probably should be, and in the near future there probably will be. (Well it'll probably look more like a monoculture until we learn that lesson for the nth time, but... yeah)
