She reads through that reply, and takes notes on possible precautions to apply to herself.
She sets meditation reminders, self-check in reminders with Yew, gives herself a "check that the reminder system is functional" tattoo on her left pinky finger, and a few other precautions in that vein. Unfortunately 'have faith in the Emperor' is ... not really something that Xanthoceras can do. She hasn't had faith in anything without understanding how it works since she was a child.
Thank you. That was really helpful! I will implement precautions based on that, and inquire with the person coming to watch my demonstration for others.
I like your question — it really gets into the heart of what I expect you want to know. Hmm. How to put my answer ...
My civilization is small, compared to yours. It felt big at the time, but our total population is only about ten billion, and we were limited to about a light year around Sol. We hadn't met aliens, there were no signs of radio signals from any other intelligent life, we still hadn't figured out faster than light travel, and so on. Also, as you know my sensors can detect Warp artifacts — and there was no sign whatsoever of the Warp. So do bear that in mind, when I'm describing our different institutions; we don't have to deal with nearly so many people, no so extreme dangers as you do.
It's hard to pin down any one way things are, because my civilization is a federation of many different polities. The main ones are the countries on Earth; a (close) majority of the population still lives on Earth. There are, depending on how you count, somewhere around 300 countries on Earth. The exact number is a hot subject of debate, because nobody completely agrees on where the borders are, or who is capable of self-governance. There are many more, smaller countries in space, ranging from individual space stations to settlements on the other planets. Many smaller countries and some larger countries join together in alliances to set various standards for how people should be treated. Those different countries are very diverse, with people living in thousands of different ways, and people moving around between them fairly freely.
But ... humans are still human. Most people just go about their lives: having families, telling stories, exchanging gossip, writing music, complaining about things, etc.. The vast majority of the population is still unaugmented humans. I was one of the relatively small fraction who uploaded, I think in part because I still probably understand the whole process better than most people, so I was more comfortable with it.
As for how it came to be that way, and my role in it ...
I suspect you can imagine what happened when I invented the universal fabricator. I de facto conquered the world, even if not de jure. Because nobody had anything that could have stopped me from doing whatever I wanted. But I didn't want to rule anything. I'm a scientist and inventor. I was working on trying to understand the principles behind the universal fabricator because I wanted to be able to make things for people — primarily, solving medical problems, and providing better food, water, shelter, etc.
So I donated the fabricators to all of Humankind. I set one base rule: that anyone could use the fabricators to move themselves away from wherever they are. Other than that, I instituted a system that allocated shares of the universal fabricator's manufacturing capacity to people, and let them trade their shares. My intent was that people could build whatever kinds of places they wanted to live, with whatever amenities they wanted, and then go there. And it pretty much worked!
The year after I released the fabricators, average happiness was up, average health was up, and people were having more children. People started building the first interstellar star ships, and both physics and materials science made huge leaps forward.
For myself, I set up a handful of countries based on how I thought things ought to be. One flopped, but the others have been mildly popular — although not as popular as some of the other countries people have started. I continue to administrate the universal fabricator network, to ensure that it remains operational and keeps up with the expanding needs of the populace. I do physics experiments, educate people about universal fabricators, work with some volunteer organizations, talk to people, that sort of thing. I live in an apartment near one of the poles of the moon, in a nice area under a crystal dome for air.
If I had to really sum up my civilization, I would say that it's ... relaxing. Everyone's needs are provided for, so everyone does what they really want to do, whatever that is.
I hope that answers your question. For my own question, I'm hoping you can tell me some things about the law of the Imperium. Do you have a process for recognizing friendly (or allied) independent human states? If so, what is the process, and what hurdles would you expect to come up in following it? If not, why not?
