Interesting the phenomenon where although the original presentation... 1. Indicates it will recognize you in the dark (https://youtu.be/mMV_LcrZtLg?t=21m29s https://youtu.be/mMV_LcrZtLg?t=21m29s) 2. An accompanying video indicates it works in the dark (https://youtu.be/K4wEI5zhHB0?t=1m47s https://youtu.be/K4wEI5zhHB0?t=1m47s) 3. The Apple website indicates that "Invisible infrared light helps identify your face even when it’s dark." (https://www.apple.com/iphone-x/#face-id https://www.apple.com/iphone-x/#face-id) 4. The parent article indicates "It uses only infrared and existing light, which means it will work in darkness without any more light than is coming off of the phone’s screen." ..that seemingly knowledgable folks can be still confused. Bringing new tech to market isn't easy, but convincing folks that it's not a rehash of existing tech is hard too.
