"I was very interested in the website at first, but then I started to worry those images at scale will have a huge effect on how modern societies think about evidence and trust," another Weibo user, Xiao Shudai, held.

To put it another way, websites like ThisPersonDoesNotExist.com may be just the beginning of this new technology, and some more devious uses may come later.
