In 2-3 decades, hardly anyone will travel on Earth.
I've heard claims that no one needs to travel today, that sound and video today provide all the experience you need. I suspect that your claim, like theirs, will fall on its face and people will be traveling just as much.
Why waste time transporting your body hundreds of miles when you can just rent a drone body at your destination?
Because the real world is very, very different from a pair of screens right up in your eyes and speakers on your ears. Assuming you can hear anything, with the buzzing. And you're even allowed to go somewhere, given how many places outright ban drones.
This is why the whole 'self-driving car' thing is attacking the wrong problem. It's like someone in 1900 trying to figure out how to clean up all the horse crap that will be clogging up our cities by the year 2000, when everyone will be able to afford a horse.
Transportation will change, but I don't foresee it going away in favor of sealing ourselves in our homes and plugging ourselves into VR headsets and acting as if we're "there" via noisy, buzzing drones.
