There's plenty of places to go. Space is literally infinite. We even have multiple options within our own star system.
As someone brighter than me put it, let's colonize Antarctica first. We're nowhere near being able to survive there, now, without regular support ships. Even with those, it would be considered a miserable existence by the vast majority of people. Tell me, where in the world would you go?
…And even if you did all you did was move human problems to some other place we weren’t built for
Sounds like you’re suggesting colonizing space with biological humans and I’m not sure why that would be preferable
Is that the goal? Immortal humans? Seems less plausible in every possible dimension (and undesirable imo) than making superhuman machines
You’ve also not solved anything like food/water etc…there’s an entropy problem that isn’t solvable.
The universe is hostile to a stable species and we’re not even stable genetically what exactly is the future people are thinking is possible?
It is literally not.
