"The problem here is not that corporate executives might build AI servants and command them to do something monstrous. They’re not in control. It doesn’t matter whether they’re benevolent. Humanity is faced with an engineering challenge: How do we shape the preferences of AIs that we can’t understand? It doesn’t matter whether or not the engineers have an ethics team watching over their shoulder; the ethicists wouldn’t have any idea how to get an AI’s preferences to align with ours, either."
