Journalist Steven Levy's excellent in-depth look at Apple's machine learning and artificial intelligence systems used throughout iOS and its other products have left some people wondering about transferring the so-called iBrain database to a new device. Apple told Levy that iBrain is local to a device and doesn't get sent to the cloud.
The explanation promoted some people to wonder if that means that iBrain has to start all over again after getting a new phone, and lose all memory of what it learned in the process. As it turns out, some of the information in that “brain” can indeed be restored and moved to a new device in a safe manner.
