In their latest iteration, Apple’s popular AirPods wireless earbuds let you activate Siri, Apple’s AI assistant, simply by saying, “Hey, Siri,” just as you can with your iPhone. With the original AirPods, a physical tap on one AirPod would bring up Siri, but the voice command is simpler. And it takes us one step closer to a world where we can talk to our AIs and they to us anywhere, anytime.
