Where is that?
Say that all who have Face Detection turned on, united by a world-wide network, and all had pictures of as many people as they would ever have, chances are high that Face Recognition would find all possible Dopplegangers or, if you don’t believe this stuff, find people who resemble each other. My idea comes from walking by a person who very strongly resembled my brother down to height, weight, and mannerisms, but I was too shocked to say hello. My brother at the time was in a school teaching a thousand miles away.
