While I do have friends who simply travel to build their brand around it (every year in my circles there's a set of "cool" destinations that you post pictures from, where somewhere like Iceland is cooler than Rwanda), I think tourists have and will continue to have the same behavior. As a tourist, you have a limited amount of time to explore. Sure you can "go off the beaten path", but that represents a risk, and while the experience may be interesting, you could also end up in a boring villa/Airbnb with nothing more than mediocre food and unfriendly people. Wasting your limited vacation time on a subpar experience is a pretty dismal proposition, so most people will take a trip to a place that's easy to navigate as a tourist while still giving enough of the local flavor to impress.

There's something to be said for trying to preserve local flavor while accommodating tourists though, and that's a line each tourist spot will have to find for themselves. Some will probably inevitably become expat party towns, while others will probably strike the right balance.
