Once we realise that reality is unrealistic, we discover that we live in a simulation. That doesn’t require spending massive budgets on scientists. But that doesn’t tell us why we exist. We can explore the possible motives behind those who run simulations of human civilisations to understand their motivations. Again, that doesn’t require scientists. There is no point in speculating beyond the obvious, because the possibilities are infinite. Modern humans place great value on their inner selves, so we may not alter our human essence once we can. Hence, the motives of post-humans could be similar to ours. And so, post-humans might run simulations of human civilisations for research or entertainment.

Research could involve running what-if scenarios. What if a giant meteor hits the planet’s surface? What if China never becomes unified? Alternatively, what if religions such as Christianity and Islam never existed? Or what if a deadly infectious disease breaks out? Countless scenarios are possible. Post-humans might be interested in running them to see how we cope. These simulations are likely realistic. After all, playing what-if with unrealistic assumptions is not playing what-if. What if humans suddenly transformed into koala bears? Some individuals might entertain that thought. And so, that is entertainment.

Possible entertainment applications include games or dream worlds that bring your imagination to life. Such a simulation may be unrealistic in some aspects, as it reflects the rules of a game or someone’s imagination. Minor changes can have a dramatic impact on future developments. And simulations of civilisations are complex. If you desire to make your imagination come true, you need control over everything that happens. That doesn’t apply to games. Unpredictable developments make games more interesting.

What we know about human nature suggests the number of simulations for entertainment will vastly outstrip those run for research. If we live inside a simulation, we should expect its purpose to be entertainment. That could be either a game or a script, thus a story someone wrote. The owner or owners may use avatars and appear like ordinary human beings to us. If reality is unrealistic in some aspects, this suggests that our purpose is entertainment, as a simulation run for research is more likely to be realistic. Evidence of control further indicates that the purpose of this simulation is not to play a game, but to stimulate someone’s imagination through a story.

We live by stories, so there is nothing typically modern or Western about the idea of using the existing technological means to run stories. We have books, theatres and films. What is more speculative is the degree of individualism in the supposed motives of the post-humans. Humans are originally social animals who live in groups. It is particularly Western to see ourselves as precious individuals. It is an inheritance of Christianity that sees each human soul as precious. That individualism allowed Europeans to organise more flexibly, which eventually made them conquer the world, so it is not far-fetched to assume that an individualist culture is at the basis of the civilisation that created us, and that we are a product of a consumerist economy.

If the beings inside the simulation are sentient, that might raise ethical questions like whether they have rights that the creators should respect. Rights don’t exist in objective reality. We only imagine that we have them. And, considering how humans treat each other, it is not a given that our creators would respect these rights even when they acknowledge them. In a realistic simulation, bad things happen to people. And if the simulation is the stage of a story, and there is a script like a film, the beings inside the simulation, thus us, aren’t sentient beings but mindless bots. We would be less than worms. Real worms at least decide for themselves how to grovel and when, so there would be no reason whatsoever for our creators to respect the rights we imagine we have.
