Caleb: Caleb quotes Oppenheimer to Nathan saying "I am become death, destroyer of the worlds". Oppenheimer, after the test explosion of the first nuclear bomb, realized the incredible significance of the scientific achievement and recited part of Chapter 11, verse 32 of Hindu scripture Bhagavad Gita where Lord Krshna takes the form of his Virata Rupa and utters the quoted sentence. Caleb is implying that Nathan's achievement in creating the Artificial Intelligence is of global consequence event that could destroy the world and the way it functions.
