I wonder whether this could be used to crack face id.

Probably not. Apple specifically said that they've tested Face ID against masks (even Hollywood quality ones). Also, Face ID checks for user attention, so a static 3d-printed would not work. I wonder though if it worked if you put a mask over your face with eye cutouts? When the devices arrive I'm pretty sure some very clever people will try to tackle this problem, this should be interesting :)

  Man are they good at marketing. They just knew this precise conversation would come up and created the perfect brief counter-argument preemptively ("hollywood quality masks").

    Is it good marketing or engineering (the latter implies both)? I guess we'll find out soon enough.

      If it were good only engineering no one would know about it

    They mentioned an infrared camera, bet they're checking temperature too.

      They're using a near infrared camera which can't see much beyond what your eye can see except for TV remote LEDs and security camera floodlights. It can't see temperature unless something is almost red hot.

      should be able to warm up a mask with a blow dryer

        You can detect a person's pulse by amplifying the right frequencies in a video, because the pressure of the heartbeat changes the color of the face almost simultaneously. You could probably fool that by giving the mask capillaries, but that would end up being expensive.

Yes, I suspect this could be a part of the solution. They'll also need a way to simulate eyeballs, in order to fool the sensor that measures if the dummy is "looking" at the device.
