iPhone X - Is ID Fooled by Distant Relatives?

Face ID in the iPhone X can also be tricked by distant relatives, at least according to a video clip that was recently published on the Internet.

Face ID in the iPhone X seems to have more and more demonstrations of the fact that it is not as secure as the Apple company wants us to think it is in reality. Yesterday I saw that a 10-year-old can unlock the iPhone X, and in the video clip below we can see that a man's phone can be unlocked by his third cousin, so a fairly distant relative.

Of course, everything is based on "teaching" Face Id from iPhone X to recognize the faces of both people, the system being fooled immediately after it was set for the first time. More precisely, the owner set it, then the cousin tried to unlock it and his face was scanned while entering the access code, so Face ID learned it as the owner's.

The same thing was done by two brothers who tricked Face ID even though they are not twins, and the iPhone X seems to have a problem with learning the faces of the users. More precisely, it seems that artificial intelligence would not be as intelligent as it seems at first glance, it could be fooled because of the way everything was thought.

Considering that the iPhone X can be unlocked by such distant relatives, theoretically anyone could trick the system to do the same. What do you think about Face ID?
