Likewise, they point to merit (which I think we consider very much like expertise) as one such fundamental concept in our society, which is very much undermined by unchecked use of LLMs. This coming not just via "cheating," but by the way in which we so quickly are willing to claim, and ourselves believe, that we deserve praise for that which the machine has created. On a wide scale, their use will not just compete with those who may not use the machine, but will destroy even our shared idea of personal merit.
Beyond merit alone, AI might lead generally to our "own cultural values becom[ing] not just decadent or debatable but unintelligible." At the end, Berg and Baskin basically say that hope is not sufficient (hope that the old concepts will be replaced with new ones); the proper attitude is to do everything in our power to preserve them in the present.
