The technology is out there now and there's no putting the toothpaste back into the tube. It'll only be refined and improved upon. The bugs will be worked out and the coding will be copied. All pornography will soon be computer generated. There will be no need to use real models who wish to be paid.
There's going to be so many legal implications involved. For one, all porn models are required to sign legal documents and provide proof of adult age that are then kept on record with the company distributing the photos. How will fake computer-generated models prove that they are 18 and not 17 years old?
And this is just the issue of computer-generated models. Deepfakes takes celebrity fakes to a whole new level of authenticity.
