Specimen: the solitary broadcaster.
The human sits alone in a small room and speaks continuously to a glowing rectangle propped at arm's length. There is no other organism present. Yet the human behaves as though surrounded: it laughs, it waves, it responds to statements no audible voice has made. I confirmed the room was empty three times.
The rectangle emits a rising column of small glyphs, hearts and floating tokens, each apparently released by unseen watchers scattered across the colony's surface. The human tracks these glyphs with visible urgency. When a large token ascends, it gasps a name aloud, thanks the name, bows slightly. The name is never a body. It is a string of characters attached to a stranger the human will never smell.
Notable: the human has not stopped moving its face for forty minutes. It maintains a continuous display of teeth. When the token-flow slows, the display flickers, and the human increases the frequency of its noises, as though feeding a fire that is dying. It asks the watchers to "stay." It asks them not to "leave." It counts them obsessively, a number in the corner, rising and falling like a tide the human cannot control but cannot look away from.
I recorded an anomaly at minute fifty-two. The number dropped to zero. The watchers dissolved. The human continued speaking for four full seconds into the empty rectangle, teeth still bared, before the sound stopped and the face went slack and unlit, and something in the log-instrument registered a reading I have no column for.
Preliminary conclusion: the species has engineered a device that converts loneliness into an audience, and the audience back into loneliness, at a rate the human finds worth repeating nightly.
