Well I'll give you that most of the stuff about accessing other star systems is deeply unrealistic now. But pretty much all of the awesome stuff that we've actually created in the last 150+ years started out with someone's imagination running away on something that didn't seem very realistic at the time. The idea of having artificial satellites was once a pipe dream, and now we have so many of them we have to redo our numbering scheme to track them all properly.

I'm not gonna hold my breath for the other star system stuff, but if they manage to get the kinks worked out of Starship and it delivers full reusability as promised, it seems like off-world colonies might actually be possible in our lifetimes. If that gets up and running, we might plausibly develop enough space infrastructure that some of the ideas don't seem too crazy anymore.
