I swapped mobile phones with my doppelganger in a parallel dimension. Face ID still works! His dimension don't know about transdimensional travel, so the photo roll on the phone I gave him is going to be really interesting to their scientists.
They don't have gen AI there either, so my doppelganger's going to tell them that any six-fingered hands are because of radiation-induced mutations caused by World War 3.
