Over the past 20 years, technology has changed the face of the planet irrevocably. Now it’s estimated that the average person spends 20 hours a week online and that’s not including the time that we spend messaging our friends on our increasingly advanced smartphones.

However, as has been the case with so many once great inventions, technology is now developing a much darker side.

The concept of artificial intelligence is nothing new. Hollywood movies like Terminator predicted a world where humans would be overthrown by machines, and they could have predicted the future, with an AI robot named Sophia even saying that she wants to destroy all humans.

Almost anything that you can imagine is possible with technology, and AI’s darker side has now surfaced in a disturbing Reddit thread entitled “Deepfake” created by “userdeepfakeapp” which uses advanced facial recognition technology to face swap celebrities and adult movie stars.

When this story first surfaced in December, celebrity victims of this disturbing trend already included Wonder Woman star Gal Gadot, Taylor Swift, Scarlett Johansson, and Game of Thrones actor Maisie Williams, according to Motherboard.

This technology also means that anyone, celebrity or not, could find themselves a victim of revenge porn.

While face swaps have been around for some time now and easily accessible on apps like Snapchat, the technology used by Deepfakes is so realistic that it’s hard to believe that what you are seeing on the screen is not a genuine leaked celebrity sex tape.
