Dude. It’s basically known Apple wanted to to both but couldn’t in time for release...it was even delayed without it.
No reason to get defensive about it. There were reports that say Apple never had intentions to put Touch ID in the X as well. It was also reported that challenges with the TrueDepth camera was the reason for the delay. Neither of us know for sure. What we do know is that Apple bough PrimeSense in 2013 and spent 4 years perfecting the kinect-like tech we have now in the X. They have also stated themselves that Face ID was the plan all along (obviously, could be saving face there) and that it is a better solution than Touch ID. Whether you approve or not is up to you to decide, but Apple has made the choice to move forward with Face ID. History would suggest that Apple would not go back in the opposite direction when they have taken a step forward in biometric security.
