Something like this indeed; imagine us in 1000 years (if we don’t blow ourselves up or something before that); we would have brain up/download, the tinniest and energy efficient chip-equivalent that can run your brain and photorealistic VR.
Even with those simple extrapolations, it’s easy to see that we can stick a few billion ‘humans’ (brains-on-chip) in a solar powered spaceship and just let it hang there for eternity or it could do a journey to somewhere. But what’s the point of a journey as inside this relatively tiny ship, these brains will live in a world (probably a clone of older earth) with a universe around it they can explore.
This seems all rather feasible given time and we would not seem very advanced from the outside; you would hardly be able to detect us at all and yet 100s of billions people live in perpetual paradise (or hell, but again; why would you make it bad if you don’t have to).
