I think AI will lead to a huge increase in fun historical games and explorable worlds. Many expected AI to democratize fiction by making it much cheaper to turn anyone's imagination into a game or movie. But we haven't seen as much additional compelling original content as expected. Lowering production costs doesn't automatically give people good ideas. It turns out editors, publishers, and studios were better at selecting promising ideas than we gave them credit for. History is different. There are thousands of fascinating worlds with existing cultures, characters, adventures, conflicts, and stories, but recreating them has been very expensive. Cheap AI will let us explore and learn from them. AI will make thousands of less familiar periods and places economically viable, e.g. you could explore the town your great-grandparents lived in and interact with NPCs. Pick a location and a year and explore. The most popular experiences probably won't be faithful reconstructions, though.
