PLANET’s setting will be Earth, seven millenniums into the future. Because I can never actually go there, I will have to create the setting in my mind's eye before I can “transfer” it to others. This is an exciting and daunting task. No one can know how far mankind will have come. You can only consider what people hope to see in the future, though history has so often proved them wrong. The courage is in the trying, I believe.
What kinds of housing will humans inhabit, what foods will they consume, and what clothes will they wear? What won’t be available, is a big question. Will “peak oil” be so on the downward slope that nothing is created from petroleum anymore? Huge considerations.
How far do you think humans will have come in seven centuries?
