At some point far in the future, humanity will populate an entire planet with custom designed species, something like the engineers from prometheus. If only there were a way to live long enough to see all that.
Maybe the future lightcone denizens are of masters of physics. Perhaps one day they get bored of building Dyson spheres and decide to tap into the past for amusement.
Maybe they have unimaginable access to such vast energies that they can capture every photon that ever left earth and effectively reverse the lightcone.
Maybe they can sample the neural state of every lived human with exacting precision and wholly create the history of life on earth down to every single human thought and experience. Every neurotransmitter flux. If you've conquered galaxies and bent physics, perhaps this unimaginable resolution of observation is quite trivial.
Maybe they'll resurrect us. Hopefully into a world palatable for us, not some hellscale dystopia horror/torture simulator the quadrillionaires of the future enjoy putting us through.
Maybe that's you now. Being resimulated.
This is all ludicrous, implausible, science fiction fantasy. But maybe your next waking moment will be meeting the future. Hopefully they have something good in store.
Be it a pale shadow or not, this is a first milestone down a path I hope we continue on.
