Verification Is Not Knowledge: The Human Cost of Automated Science

As AI systems begin to produce verifiable scientific outputs—from mathematical proofs to medical treatments—a philosophical tension arises: is science about achieving correct answers, or about human understanding? A new essay argues that relying solely on automated verification risks a 'view from nowhere,' where results exist without the social accountability, epistemic taste, and human judgment required to integrate new findings into the canon of knowledge.
