"I suppose—one has to suppose—that to the AIs, love is just one more quantifiable entity in a universe of quantifiable entities. Probably it’s as basic to them as a bit of clockwork; the right neurons firing, a few chemicals in the right combination. But then again, the same can be said of life itself. The sweet, living Earth, with all its countless green fronds and numberless beating hearts, is all just clockwork and chemistry, all eminently quantifiable and understandable. That doesn’t stop it from being something amazing and magical, measureless and infinite."
