Is this self-sustaining AI civilization pre-RSI or post? Because if it's post, then I agree: we can't imagine what would happen because it's literally the singularity.

If its pre-RSI, then we already have Ilands and its a big nothing burger? There's no (likely) path of escalation from an AI social network to bioweapons or them hacking POTUS's nuclear codes? That's a very big leap and if you want to support your claims I would be willing to listen; but I'm not seeing it.
