I'm pretty late to leaving a comment, so it won't get a lot of exposure. Let's just leave these people the fuck alone. What threat are they under? Curious assholes like us. There are probably less than 1000 people on that island, all descended from people tens of thousands of years ago. There are more people than that that visit an Apple store on a Tuesday before 2pm. Leave them alone. We don't need to assuage our 10…
The disease part can be handled today. We could go visit them in hazmat suits. And I know I'm being really generous when I'm comparing the modern world to benign aliens, but properly managed (as access to the island already appears to be) surely we can approach them in a decent way?
That they violently defend themselves is of course a highly complicating factor.
I guess all I'm saying is that not establishing contact is also a choice that we're making on their behalf. Is deciding that they can't parttake in modern society any more OK than deciding they must? Can we not contact them in a way where they get to choose?
Edit: I certainly agree that we as humans have an absolutely horrible track record on these kinds of things. But it's been a while now, hasn't it? Can't we pull this off by now? These guys are our brothers and sisters - should we at least not have a chat with them to see if they really want to be left the fuck alone, or if they might want to not die whenever they get an infected wound, or half the time they have kids, or whenever they break a leg? Hell, it might well be that some of them want to be left the fuck alone, while some would like to see the world. How come those latter ones have to stay on that island just because we say so?
