They always make the same mistake when talking about high-speed travel.
Really fast spaceships would appear to take billions of years to reach another galaxy, for observers stuck on Earth. However, the occupants in a relativistic spaceship could experience something completely different: their destination arrives at the blink of an eye, and it (the galaxy) undergoes accelerated ageing, while the passengers stay young.

It seems like a pretty bad side-effect of interstellar travel when everything else gets old around you. And every journey is a one-way trip into the unknown.

Every trip is always a trip into the unknown...

I think the idea that a space faring civilization would be zooming around interstellar space in spacecraft is sort of absurd. Until you can precisely deconstruct and reconstruct matter all the way down to the subatomic level, interstellar flight is a one-way ticket with no hope of return...

In my opinion, it's possible to be at all places at once, but not while living... Teleportation is the scientific equivalent of conjuration.
