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).

Exploration seems like a natural way for civilisation to live, but that's because exploration is needed to expand knowledge and grow more intelligent, we as a civilisation mostly became obsessed with intellect dozens generation ago, if not less, and gathering knowledge and exploring for us seems so important right now. It might be less important if important at all for species who have been intelligent for a long time and gathered orders of magnitude more knowledge than we do.

Related question is do species really need intellect at all and how much. It could be that the main purpose of intellect is to increase chances to survive, but what if civilisation already figured survival, will they even need to stay intelligent? Maybe their goal is to be happier or maybe have billion orgasms per second.

Another more obvious reason to explore the universe is lack of resources, at least Earth was mostly explored to be exploited. If resources are solved, one reason to explore less.

Most of the financial impetus for exploration comes from the promise of access to scare resources. But if you have the technology to traverse the stars then your species is either able to harness unfathomable amounts of energy such that you can bend space-time or you've done some kind of wild genetic engineering/cybernetic enhancements to the point where it's not really bound by the limitations of whatever biology its planetary evolution set it up with.

In both cases, they would have the means to functionally be living in a post-scarcity society. Either their consciousness is stored in some kind of long-term solid-state storage that can survive millennia long trips through space or energy is so cheap and available that it's hard to imagine them needing to keep going and searching to find more stuff. After you've explored and catalogued a hundred planets it's hard to imagine any real impetus to keep going.

Human civilization is already projected to cap out in population at around 11 Billion, and that's driven primarily by cultural and economic factors deriving from technology around access to healthcare, education, and other sources of diversion/entertainment/fulfillment. The idea that an advanced civilization must necessarily keep growing and growing in size doesn't seem to hold up for our own experience on Earth.

Or, of course, if we manage to make infinite energy on earth, we don't even have to shoot anything into space; we can simply stack the earth full with these brainframes and stick it out until the sun starts to fail. Besides we ending humanity too early to get there, I find it hard to believe this will not, inevitably, happen.
