The weird thing to me is that apparently we have so many people on HN that consider themselves worth the effort to make full 3D renderings of their faces just to unlock a phone. Unless you were Osama Bin Laden, it seems highly unlikely anyone would go to the trouble. If you are that kind of person, you’re probably going to be protecting your information with much more than Face ID.

There would be more than enough detailed photos and videos of politicians, celebrities and business leaders floating around for a skilled sculptor to recreate their faces, there'd be some high value targets there.

They're not magic. You can make a fake with enough effort. But it's a lot of effort.
