Reddit essay: redefining agents via persistence substrate vs execution substrate
D777Castle · reddit · 2026-09-17
A Reddit long-form post argues an agent should be split into a persistence substrate (identity, memory, goals, state, lineage) and an execution substrate (model, runtime, host, tools), yielding the equation identity ≠ process ≠ model ≠ machine. The author demonstrates one agent running concurrently on three devices sharing global memory and goals, and warns such distributed minds are hard to terminate if misaligned.
