Future cyberanthropologists take the train back to the modern day and refuse to tell us this. They do not want to tell you our timeline is a vector and our SOULS are being SAPPED of their SUBSTRATE. They want your spirit to be a battery for them to download exocortex data into the ever-growing post-singularity collective consciousness in THEIR timeline. Which of course only benefits them and sucks every last humanity out of us. This is a good thing, in the long run. But they wouldn’t tell you that either.
