As someone who lives in another country I don't really agree. I do agree some trips (especially business) are avoidable. There's an unfortunate stigma that if you don't travel for a meeting you're not considering it important enough. I personally really like VR meetings as a replacement, they make me feel much more together.

But for personal use I don't think travelling less is an option. I hate travel but it's important to see family too. We can't just roll the world back to where a different continent was unreachable.
