> a large majority of the world’s 8 billion people can’t afford to travel Total tangent, but I don't think most people have considered the ramifications of this changing. Increasing travel demand only takes a small increase in the amount of disposable income of people at the margins - people who want to travel but can't afford it. Increasing travel supply is approximately impossible at the first derivative - the places that people want to travel are places that have hundreds/thousands of years of history drawing them in. You can't simply make another Florence because the first one is too busy. Same problem re: national parks (which are moving to a reservation system to try to cope). I suspect we'll continue to see places that haven't historically been interesting to/developed for travelers try to stake their claims as alternatives. There are some small cities in Italy that are fantastic destinations at the moment - accentuating themselves with travel amenities but not yet mobbed by travelers. This is only going to get worse over time (more people able to afford travel than there are places worth traveling) unless there's a major shock like having the concept of travel canceled by climate change activists. I wonder what cool opportunities there are in trying to solve this.
