Of course it&#x27;s frightening. But it&#x27;s frightening in an exhilarating sort of way. I am sure that most of us would love to get our hands on that type of data, and the tools to work with it. And the benefits can&#x27;t be denied - it&#x27;s not mainly for security, which is the main argument for selling surveillance to us here in the west, but optimization. Of everything (security, too, of course, as mentioned in the article- but terrorists are only tangential). And it&#x27;s a trade-off - if it&#x27;s worth it remains to be seen, and the answer will probably always depend on who you ask. Personally I haven&#x27;t really made up my mind yet.
