A decade ago, if you claimed that your phone could make calls on your behalf, you’d be carted off to the loony bin to live the rest of your life in a padded cell. This year, Google made it look easy at I/O 2018 with Duplex, where the Google Assistant was capable of making a phone call on your behalf and even sustain an almost human-like conversation (complete with fillers and everything). Yes, some of it appeared to be a gimmick, but it did set a precedent. The company stated that the feature would be rolled out ‘soon’, but didn’t specify a timeline. We didn’t hear much about it until now. Today, Google released another video that demonstrates Duplex’s prowess. Check it out:

The primary difference between the calls made at Google I/O and the video above is that in the latter, the Google Assistant identifies itself as the Google Assistant, which wasn’t the case last time. The change was possibly implemented to comply with local regulations. Google also stated that the feature will not work in the state of Texas owing to local laws.
