AI Customer Service Beats 83% of Humans? SoftBank and Sierra's Experiment in Japan

At 2 AM, the streets of Tokyo were deserted. LINE user Kobayashi was anxiously typing "data plan anomaly" into his phone screen. After waiting for over ten seconds, a smooth Japanese reply popped up: "Dear user, we've checked and found that your high-speed data allowance for this month is exhausted. Would you like to purchase an acceleration pack immediately after speed throttling? Current discounted price: 300 yen/1GB." No transfer to a human agent, no waiting, not even a "typing..." indicator. Kobayashi completed the purchase quickly, taking less than three minutes in total. He didn't know that there wasn't a single human on the other side of the screen—this soft silver brand called "LINEMO" had just successfully executed a live AI customer service session.
