The sparring began when Siri got sassy about Google Glass, as noticed by Twitter user Sean M. Brage. "I think that Glass is half empty," the bot responded when asked about the wearable computing technology. (It turns out that the vindictive dorks at Apple programmed Siri with a bunch of slams against Siri, a few of which can be seen over at The Verge.)
In response, Google responded with the following quip, attributable to its headset: "Siri, it's not you, it's me. You see, I just met Google Voice Search and fell hard for her. She doesn't just listen; she understands me." (It's unclear if Google's Voice Assistant actually says those words when prompted by a user; a Google spokesperson relayed them to us on behalf of Glass, which is still in beta and not yet available to consumers.)
Surely, some of the fascination with this verbal sparring between two non-sentient beings has to do with the fact that it's the last Monday before the end of summer. Or maybe some tech geeks just like watching female proxies fight. It certainly wouldn't be the first time.
