The story is a science fiction - meandering through psychological gorges and therefore often times slow - thriller. So, it might be helpful at times to watch and read some of the material offered to give some background to the more theoretical parts of the story.
This chapter has a preoccupation with the simulation argument and, indirectly, the Fermi Paradox. I am fascinated by both of these concepts because they are such great treasure troves for telling wild stories. Like most of the materials used for the background of this story, I don't fully comprehend them and, at times, I find them a little frightening. However, I have the wonderful childish ability to just not care that much. So, it is better you muddle around, watching the videos and reading the materials, as they will be much better at getting you confused and terrified then I would.
NOTE: I think you should be a little careful and not get too carried away with these ideas. Fascinating as they are, they can unhinge you from reality if taken too seriously, and that isn't a very good idea.
I have included some Terrence Mckenna links. He and Rupert Sheldrake have been melted into one character, Rupert Mckenna, who I have an undying love for. I don't understand their theories and I can't take them very seriously at all, but I just love their maverick nature and I can't help but think that although they are quite probably mad as hatters, they are onto something. Again, like the other theories, read them, have an open mind and like everything else in this world, make up your own mind.
