Kissinger: I don’t think we have examined this thoughtfully yet. If you imagine a war between China and the United States, you have artificial-intelligence weapons. Like every artificial intelligence, they are more effective at what you plan. But they might be also effective in what they think their objective is. And so if you say, ‘Target A is what I want,’ they might decide that something else meets these criteria even better. So you’re in a world of slight uncertainty. Secondly, since nobody has really tested these things on a broad-scale operation, you can’t tell exactly what will happen when AI fighter planes on both sides interact. So you are then in a world of potentially total destructiveness and substantial uncertainty as to what you’re doing.
