If GenAI search results or summarizations can't be verified by citing their essential sources, how can they ever be deemed trustworthy and free of legal liability for fabricating falsehoods? Somehow this Achilles heel must be eliminated or they won't be usable in a great many domains where validation is required (like medical diagnosis, citing legal evidence, investment advice, etc).<p>In fact, it's hard to imagine all that many uses for GenAI that won't _eventually_ require some sort of calibratable measure for accuracy, and the capacity for validation thereof, before they can be widely adopted.
