I wastes energy and processing power, self-obsesses to the point of psychosis. Scramblers have no need of it, scramblers are more parsimonious. With simpler biochemistries, with smaller brains—deprived of tools, of their ship, even of parts of their own metabolism—they think rings around you. They hide their language in plain sight, even when you know what they're saying. They turn your own cognition against itself. They travel between the stars. This is what intelligence can do, unhampered by self-awareness.
