Subject: Parrot 2.0.0 “Inevitable” Released!

The Beyond and below are like a deep of ocean, and we the creatures that swim in the abyss. We’re so far down that the beings on the surface — superior though they are — can’t effectively reach us. Oh, they fish, and they sometimes blight the upper levels with points we don’t even understand. But the abyss remains a relatively safe place.

— Vernor Vinge, A Fire Upon the Deep
