That's why I choose to believe that FTL will be possible at some point. Otherwise we may as well be the only life in the universe, the rest is dead and pointless. If we can't leave our solar system, our entire universe may as well just be our local system and everything else is just neat wallpaper.
My money is on a quantum theory of gravity unlocking the ability to cheaply warp space.
The Voyager is nowhere near max speed, nor is current biological age the final limit on human life span. If you survive another 500 million years or so, you might meet some aliens then. https://grabbyaliens.com/
If FTL were possible, causality breaks too. Plus if there's other life out there who have discovered FTL, we shouldn't even be here. Don't get your hopes up for more than a tiny portion of the universe ever being explorable.
