Idea for a sci-fi story?
A young musician lives in a squat at the centre of a thriving arts scene in a great and sprawling city of the mid-twentieth century. However, a meeting with a cynical A&R person leads them to discover the truth. It is not the mid-twentieth century. It is the future. The birth rate has plummeted, but human longevity has been solved and people now live for hundreds of years. But, as a result, culture has stultified. So a new young generation has been created using cloning and placed in an simulacrum of the culture that produced the upheavals of the twentieth century. Their world is a theme park. The question is, do they want to stay in their artificial but artistically satisfying environment, or break out and change the world, as they've always claimed they wanted to.
