Deepfakes are simultaneously both an amazing technological achievement and also scary as hell. The potential for movies and VFX work is huge, as has been proven by a number of YouTube channels showing deep fakes vs the CG versions of characters that have reappeared in various Star Wars movies. But there are obvious nefarious implications of such technology, too.
While the recreations of deceased actors in movies are most definitely fake, deepfake videos of those still living are not always so obvious. Tech gains like Microsoft and Facebook have been working on counter-technology to spot deepfakes to help prevent the spread of misinformation online. A group of researches from UC San Diego has proven, though, that they’re far from perfect.
