I'm wondering whether Apple sees this technology totally replacing TouchID, or if they will continue to offer it in the next 3-5 years on some devices?
Word on the street was that they were planning on including both TouchID and FaceID in the X, but scrapped it earlier this year due to low yields during mass production[0].
Sure, because facial recognition has many applications outside of unlocking your phone, including the trivial ones like Animoji and the new selfie features that were demoed at the Apple event.
