There's an old documentary where a film crew transported some of those "uncontacted tribe" guys to central London. Rather than being in awe of jet engines or networked internet, the tribesmen guys spent most of their time admiring house construction. "You're telling me there's METAL inside these walls?" I guess we tend to appreciate what we can understand.

I'm pretty sure this has been debunked as an online myth, and no such documentary exists. If you can show otherwise, I'd love to watch it

The documentary is real. I don't remember a house construction scene but it's been over 10 years since I watched it. It's not an uncontacted tribe, but tribes from Vanuatu and the Solomon Islands.
