I mean, the ideas are there. The scope of the project is probably too big to reproduce for now, but eventually it will be accessible to your average spammer / scammer. We will get there. We won't be able to get these tools locked, make them exclusive for a certain type of responsible AI specialists. Someone will spill the beans, the models. People with bad intentions will reproduce these results. To me, the real deal is how we will manage these outbursts when they happen.
I assume discriminative models will solve the problem for a while, but as with Generative adversarial networks, you will be able to train models that are harder to discriminate against. I posit we're in for a big societal change (maybe more a content crisis) sometime in the next 10 years. Pretty sure we won't be able to keep it from falling in bad hands.
