What is currency but a proxy for time spent/labor? Today, different peoples labor is exchanged for different values of currency.

If we reach the era where labor isn't necessary for the majority of daily life, what value does labor/time offer anymore? Why would a seemingly very low value commodity (labor/time) be used as a value exchange medium?

There may be a new thing that is developed as a pseudo-currency, based on some other intangible-value-made-tangible, but it wouldn't be a stand in for labor/time in this entire very made up, very simplistic scenario.

Something else would carry value, assuming the entire society is into personal possessions at that point. This may evolve into a communal situation for all we know. Post-need generations would have no need to accumulate. There surely may be some experience, travel, etc that may drive some, but even that may be trivial.

There is zero reason to apply your personal beliefs about the past to future societies that don't have the same restrictions or priorities.

You can add furniture that is removable replaceable, not permanent. That is the better idea.

Doesn't matter if the background is pure dark sky, the apple UI is trash in comparison.

Just start writing sections. Get things on paper/screen. Its a lot easier to remove something than try to add it later.

Flesh out scene descriptions, and what happens in each chapter.

Then fill in dialogue points you want to hit, then flesh out the writing around those.

Being alive at any point in time might make you sad about it. got it.
