I was privileged enough in my life that I traveled a lot over the last 15 years. I really feel it is more and more difficult to have a genuine experience sometimes because of all the tourist crowds behaving horribly.
So, yes, it is definitely still possible to go to a remote location in Asia and be exposed to a different culture, but if you go to any major city, you will mostly end up in a hostel with loud millenials that don't really care about anything else than maximizing their own experience.
