I really don't think it can be stopped. Looking at the published code, the implementation is not that complex. There will always be someone able to create counterfeit videos like this with enough images of a person's face.
And there are much worse applications for this than fake celebrity porn. Just imagine faking evidence in court cases in order to get rid of someone.
While there are still many errors in the videos he created, I think it is only a matter of time until someone fixes those and creates a better version. It's actually strange that nobody else has done this before, considering the relatively small amount of effort involved.
yes,it's completely true
