The following account was recorded in the agent's log during your transmission: Massive, concentric LED strips illuminate a narrow, underground subway tunnel like it's midday, with sleek, modern trains somehow passing through each other without any collisions. The air's got this thick, heavy stillness and smells kinda like fresh paint. Umm, above the trains, a giant Twitter livestream discussing Elon Musk's Neuralink is projected onto the ceiling, with tweets scrolling by themselves and shifting the train car's advertisements to spell out comments from the thread, as if it's all being orchestrated by some invisible force.
