This is also incorrect. It's often not ethical to cause harm, and it can be counter productive in the right circumstances, but there's absolutely nothing that makes "causing harm to others" always be against an intelligence's goals. Humans, for example, routinely cause harm to other species. Sometimes this is deliberate, but other times it's because we're barely even aware we're doing so. We want a new road, so we start paving, and may not even realize there was an ant hill in the way (and if we did, we almost certainly wouldn't care).
