They still haven't even developed the technology needed to shield human beings from the radiation we'd be exposed to in the interplanetary medium, let alone interstellar space. Elon's Mars dream is a fantasy until that problem is solved: he'd die screaming from a fatal dose of neutron radiation before he ever got there.
The radiation problem can probably be licked somehow but the idea of an interplanetary/interstellar empire is a fundamentally materialist, utopian fantasy and it's not going to happen to any significant degree. Exhibit A: the behavior of materialist utopians like Elon.
