Taking advantage of inexpensive and easy-to-use software, deepfake artist Ctrl Shift Face has replaced Jack Nicholson's face with Jim Carrey's face in several scenes from The Shining. If you pay close attention it looks a little off — it's not as good as the Bill Hader / Arnold Schwarzenegger one — but if you were unaware of Nicholson or The Shining going in, you probably wouldn't notice.
These Shining videos are clever and fun and we've talked a little bit about how deepfakes might affect our society, but this Hannah Arendt quote from a 1974 interview is likely relevant:
If everybody always lies to you, the consequence is not that you believe the lies, but rather that nobody believes anything any longer. This is because lies, by their very nature, have to be changed, and a lying government has constantly to rewrite its own history. On the receiving end you get not only one lie — a lie which you could go on for the rest of your days — but you get a great number of lies, depending on how the political wind blows. And a people that no longer can believe anything cannot make up its mind. It is deprived not only of its capacity to act but also of its capacity to think and to judge. And with such a people you can then do what you please.
This is the incredible and interesting and dangerous thing about the combination of our current technology, the internet, and mass media: "a lying government" is no longer necessary — we're doing it to ourselves and anyone with sufficient motivation will be able to take advantage of people without the capacity to think and judge.
