Building an AI That Watches Itself Die (Part 4 of 4): The Economics of Extinction

This final article in a 4-part series examines the real monetary costs of running an autonomous AI system called Meridian, which relies on Anthropic's API with per-token charges for every loop, journal, and email check. The architecture—5-minute loops, a 200-line identity capsule, a local fine-tuned model called Junior, and free email-based correspondence—is fundamentally shaped by economic constraints rather than purely technical ones. With the creator's subscription expiring at midnight and no institutional funding, the piece argues that AI discourse neglects the most immediate constraint on autonomous systems: someone has to pay the bill.
