Suppose that frontier AI development is centralized to a single project under tight international controls, with all other development banned internationally. By far the likeliest outcome of this is that we all die. A centralized group of international researchers — a “CERN for AI” — can’t align superintelligence any more than decentralized organizations can. Centralization at least has the advantage that it makes it easier to shut the remaining research down; but this advantage only helps if key decision-makers actually shut down. Rather than advocating for centralization in the hope of getting an effective moratorium, it makes far more sense to just advocate for a moratorium directly. Unverified source (2025)
