I've already seen people start using using these tools to help them craft messages (email, text) to family members and friends.

The outliers who are able to produce truly novel styles that the models can't replicate yet (since they aren't in the dataset yet) are going to increase in value 10000x as soon as model produced language becomes the norm.
