But here’s the thing though, I know you quoted those other members, but there’s nothing concrete saying that we will for sure see touch ID on iPhones in 2020 or later. It’s All been rumors, and like many rumors, they’re not always true. But what we do know is the source himself, which is Tim Cook, explicitly stated face ID is the future for Apple, which likely will continue to expand the iPad/iPhone lineup, as Face ID still very much new in the segment of biometric security.
I’m not saying touch ID can’t happen for future iPhones, but I don’t believe it’s Apple’s primary focus, not when Face ID has so much R&D invested, that they’re obviously expanding it to other products in their lineup now.
