Credible commitments solve the governance problem of bilateral dependency: when parties cannot rely on trust or goodwill, they can rely on mutually costly investments that align incentives. The concept distinguishes cheap talk (costless utterances signaling nothing) from genuine commitment (costly actions signaling intent). In the AI age, credible commitments take three forms: organizational (firms investing in evaluation processes that reduce output), industry (platforms submitting to portability standards that constrain freedom), and societal (governments funding transition support demonstrably expensive enough to signal genuine intent).
