and the timing for this essay drop matters here: anthropic is preparing to go public. an IPO means asking public-market investors to underwrite a company whose future value depends heavily on the assumption that frontier capabilities will continue advancing, while the cost and physical difficulty of producing each new generation keeps increasing. if the actual development cadence is about to become more visibly constrained by hardware and infrastructure, you need a story for why that is happening. "we have reached the point where responsible AI development requires us to pace the frontier" is an extremely good story, even if the real reason for pacing is due to physics: they simply cannot build the necessary infrastructure at the current scaling pace.
