Four rationalists are arguing about Dath Ilan. Three of them argue that Dath Ilan has lab-grown meat, to reduce all possibility of suffering, since Yudkowsky cares very deeply about suffering and would not allow even a small possibility of large-scale torture, even though he thinks most farm animals are not sentient. One of them contends that Dath Ilan has animals genetically engineered to feel no pain or distress, farmed and killed humanely, because Yudkowsky cares deeply about the quality of food matching an ancestral diet. After a while, Yudkowsky himself shows up in the thread, and simply says that the fourth rationalist is correct. One of first three rationalists says "that argument does not screen off authority, and it's still three against two".
