How Long Should an AI Agent Live?

AI 智能体应该活多久？

Tomasz Tunguz argues perpetual agent sessions rot from context decay and security exposure—a March cold can haunt your calendar in November, and long-lived read/write access invites poisoning attacks. He proposes a daily coordinator that resets every 24 hours, delegates tasks to ephemeral specialists that live ~30 seconds, and saves durable preferences to a local file at midnight. Most bots today don't perform this sleep cycle automatically.

Why it matters: Tomasz Tunguz offers a concrete architectural stance from a VC perspective: a daily coordinator with 24-hour resets. The argument is research-backed, not hand-waving. Score capped at 78 because this is a single blog post opinion, not a product launch or paper.
