All the messages and photos are in the cloud anyway. Doesn’t make sense.Apples whole take on AI is that it is done on device for privacy. Your data stays on device. That's what differentiates them. They have a Cloud version that has privacy built in(and can be verified by third parties), but that requires Apple's servers and money to run, for much bigger requests and wouldn't makes sense for something so simple that could be built on device that has the processing power to run locally.
