Uh, we have.
You're assuming that they've lived for 65,000 years with no social or cultural or technological upheaval within their own little sub-civilization. While at that same time drawing arbitrary end-points in ours.
At this point, they're only surviving because of the benign interests of outsiders. Do you really think they could survive a hypothetical contest of "what society can survive the longest?". If our culture hadn't evolved to accept and respect indigenous people like this, or if there was any economic value on that island, they'd be dead or subjugated by now. So how can you claim that they've figured out better civilization survival instincts than the rest of the world?
