We need (very) high fidelity virtual reality to save the planet, making traveling superfluous. I'm afraid we're still far away from that development.
No wonder so many HN comments are grandstanding about how they dislike or don't need travel: they aren't talking about meeting other people or experiencing other cultures. They're just talking about weekend travel packages where they're shuttled around to take some pictures.
How incredibly boring.
Your VR idea like saying you've been to Prague because you spent extensive time in Google Maps street view: I wouldn't even bother.

At this point I'm most excited about travel where I know somebody who lives there and can make those connections for me.
