How they were made: RepresentUs worked with the creative agency Mischief at No Fixed Address, which came up with the idea of using dictators to deliver the message. They filmed two actors with the right face shape and authentic accents to recite the script. They then worked with a deepfake artist who used an open-source algorithm to swap in Putin's and Kim's faces. A post-production crew cleaned up the leftover artifacts of the algorithm to make the video look more realistic. All in all the process took only 10 days. Attempting the equivalent with CGI likely would have taken months, the team says.

Singer talked about how AI now has four big "superpowers." Pattern recognition is the most common, and this is used in many domains, including image recognition, speech recognition, and fraud detection. It can be a universal approximator, as it learns the correlation between input and output, and is able to make predictions about results, which allows it to be used for simulations for things like particle movements at CERN or flight routes, using much less power and much less time than conventional simulations even if it's not quite as accurate. It is good at sequence mapping, used in things like cleaning DNA sequences or language translation. And it works for similarity-based generation--creating the next examples of something, such as creating voices, photos, or video.
