A study found AI-generated peer reviews exceed human-written ones across all measured dimensions—despite peer reviewers being paid professionals with domain expertise. Peer review is the institutional machinery that validates scientific claims. If AI consistently produces more thorough, accurate, or useful feedback at near-zero marginal cost, the economic logic for maintaining human review panels collapses. This could accelerate both the quality and speed of scientific publishing while eliminating a key human gatekeeping function. The question is whether journals will actually adopt these systems given the professional incentives and institutional inertia protecting the existing reviewer ecosystem.
