Personally I don’t think it’s likely that FP will go that way. Many vocal FP users are very privacy minded, so they reject a security risk like a fingerprint sensor.
If someone stole your phone all they had to do is find a fingerprint on the glass of your screen and already they can 3d print a finger to unlock your phone.
Not to mention a scanned fingerprint is just more personal data that the big companies and government agencies will be able to collect through your phone.
