Nothing worse than a story that's structured so heavily on a reveal that pretty much everything leading up to it is basically procrastinating.
Can't tell you how many stories would work better if the big shocking reveal was the starting point.
One area where I can see AI really taking off is topographical 3D modeling for open world maps. It's probably already done in a primitive way, and it will be harder to draw a line between acceptable and unacceptable practices when you're talking arbitrary textures and polygons that are not really supposed to exactly reproduce known landscapes.
