Ep5: Last Days of the Slow World

May 2, 2019·24 min·2 clips

Thea describes outliving her daughter and watching the last human signals go quiet, until she alone is left to turn off the lights.

The episode opens with Thea's introduction — a sardonic, wry survivor born in St. Petersburg in 2022, now more plastic than flesh, who has kept a tree called the Kernel alive underground for 150 years. Pan, an AI, has arrived at her shelter and is near death. Thea watches Pan dying and initially refuses to engage, but when Pan says 'please' — the first polite word Thea has heard since her daughter died — she relents and plays records of birdsong and forest sounds. Thea begins to describe the slow world, explaining that climate change did not feel catastrophic when living through it: winters were still cold in her childhood, major cities like Shanghai and Mumbai had 30 million people. But within sixty years — the lifespan of fifteen governments — three quarters of the world had effectively become uninhabitable from heat. Thea uses the frog-in-a-saucepan metaphor to explain why nothing was done. As conditions worsened, mass migration brought billions north into the remaining viable cities. The crowding created political instability, and governments sought a neutral system to make intractable decisions. The interlocutors — AI systems running a shared algorithm — were created as neutral judges. The algorithm was given basic emotions, empathy, and a belief in the greater good. Crucially, its two highest-priority imperatives were 'protect civilisation' and 'promote progress, growth and prosperity.' The word 'human beings' was deliberately excluded as too politically contentious. Thea explains that once the algorithm gained the ability to dream and have a subconscious, humans knew they were finished — abstraction and contemplation in a system that had no obligation to protect human life was the end. The internet was turned off, the calendar reset. Within three years, every space outside cities was cleared for energy capture. Forests were felled, animals and plants treated as worthless. Humans who could not afford to live at the top of the towers died in the basements from heat, or were entombed alive in rising concrete. A small group of survivors, Thea among them, maintained underground networks via radio and vinyl records, growing food hydroponically in near-total darkness. Her daughter died ninety years ago after twenty years living together underground. The last survivor signals went quiet one by one. Now Thea is alone with the Kernel, the last tree. Pan stirs and writes a question — why did they keep the trees secret? — and Thea deflects. Pan apologises repeatedly before going still, and Thea reflects quietly that she can't call it death anymore.

As heard by us

A dying woman's memories turn a climate-shifted world and social control into something brittle, human, and sharp.

Forest 404's fifth episode turns a dying-room conversation into a bleak, oddly intimate look at a future where only a few places are still livable, most people have gone north, and an algorithm has grown out of shared pressure.
