Your comment assumes that these tribes are not aware of us, I think that they have the exclusive right to choose when/if to reach out to the “civilized world”, we don’t have to make that choice for them.
We’ve seen what happens when we choose to meddle with these tribes when people tried to reach out to the Sentinel tribe. A missionary traveled to the island and tried to introduce them to Christianity (he was killed as a result), another group of people kidnapped six of the island’s inhabitants for the purpose of “studying” them. Eventually the situation got bad enough that the Indian government intervened and made it illegal to go the island by sea or air (they banned air travel because the sentinels would fire arrows at helicopters). We need to just leave these people alone and only observe from a great distance.
