Will the real-life version of Skynet model its Terminators after real people? That’s up in the air, as currently existing AI is already capable of crafting convincing faces all on its own. Software developer Philip Wang has launched a website called thispersondoesnotexist that proves this, allowing visitors to generate incredibly convincing but falsified human heads on every page refresh with the help of a powerful GPU and NVIDIA machine learning code. “I have it dream up a random face every two seconds, and display that to the world in a scalable fashion,” Wang told me. “Nothing fancy.” The website uses an implementation of machine learning known as Generative Adversarial Networks, or GANs. These programs “learn” from a large number of training inputs—say, real human faces—in order to produce new examples. Thispersondoesnotexist.com uses code previously released by Nvidia researchers on GitHub. “Most people do not understand how good AIs will be at synthesizing images in the future,” website creator and software developer Philip Wang told me in an email.
