I don't understand why. If someone has gone to a blockbuster movie in the last 15 years, they're very familiar with the concept of making people, sets, and entire worlds, that don't exist, with photorealistic accuracy. Being able to make fictitious photorealistic images isn't remotely a new ability, it's just an ability that's now automated.
If this is released, I think any damage would be extremely fleeting, as people pumped out thousands of these images, and people grow bored of them. The only danger is making this ability (to make false images) seem new (absolutely not) or rare (not anymore)!
