A lot to play with for the near future here with the resources of the solar system - think of all the unique cultures even just the early habitats swarms will spawn!

And even without major breakthroughs I'm sure some will try to go interstellar AI uploading, some form of hibernation or even a generation ship. Or Nuclear Salt Water Rocket at a couple dozen % of the speed of light, so the trip won't take more than a few decades, which might be doable with some decent life length ehnacement - possibly even a round-trip! :-)
