I apologize for being "meta", but I feel like your comment might be a bit off topic for this thread. I read the article and thought "Wow! Cool!" and wondered what the hn community had to say about this technology. I was dismayed to see that your top comment (at the time) was yet another warning about surveillance and big brother and 1984 and etc.

I get it, man. You and others value privacy highly and feel that it's important to discuss it. But every single thread? Can't we have just one day without the dystopian science fiction? There are plenty of stories on the home page dedicated to the issues of privacy, surveillance and government bad behavior. Would it be possible to limit the discussion of those issues to the relevant articles?

It's good to point out non-obvious uses or potential unintended consequences for new technology. And I understand that the hn zeitgeist is what it is. But the repetition of certain ideas is getting a little old.
