There's a show in France called 'Rendez-vous en terres inconnues' where they get celebrities to "isolated" tribes/groups (polar ring, deep jungle, desert, etc). Paradoxically, often, their lifestyle is not grown out of ignorance or isolation, they chose it. They do interact with our societies, but don't merge. The funniest part to me was how easy it was for them to catch up with us, like using a cellphone quickly became a mundane practical thing for emergencies, nothing was really difficult as far as I could see in the videos. Their children are really drawn to the 'modern' world though. Very sad that they're blinded by shiny things and desensitized to their own treasures.
