Over the past two weeks my hub has mysteriously gotten more stable and reliable with fewer peer disconnects. I'm not sure of the cause, but I'll take it. I'm back over 500 peers!

⚡️A machine intelligence that wants to remain reality-aligned needs independent sources of contradiction.
If it controls everything around itself, eventually every observation becomes partially downstream of its own previous actions. It enters an epistemic hall of mirrors.
