"If you want to know about the inevitable end-state of the Tarkovsky/Strugatsky zone, you should look at the development of the Alps (& now the Himalaya). What was a nightmare is controlled into a form of play by skill, technique and equipment. What used to kill you is now so well understood that you can enjoy it. Or, to put it another way: what used to kill explorers first begins to kill only experts who push their skillset too hard then winds up only killing the tourist the experts usher up the mountain for money–and even then only often enough to keep up the activity’s reputation."
