James Long: Sandboxes are about unbounded resources, not security
Vjeux · x · 2026-08-22
James Long shares his realization that the primary use case for sandboxes is not security, but rather providing unbounded resources limited only by budget. He notes feeling constrained by a single device when running agents (e.g., crashing with 3 concurrent typechecks), whereas their Slack bot feels frictionless because the location of computation is abstracted away. This experience drives his desire to replicate this boundary-free computing locally.
