&gt; <i>Under this reasoning, most all privacy is as good as dead and we are just waiting for the technology to get here.</i><p>Because it is! Thank you, somebody finally noticed. You can&#x27;t preserve privacy and push technology forward, it&#x27;s either-or. The best we can hope for is, if we chose to continue on the path of progress, that we&#x27;ll establish social customs around expected privacy, that will amount mostly to &quot;gentlemen turn around and do not look when a lady is undressing in a shared room&quot; and to the privacy of correspondence (&quot;we obviously can read your mail, but it&#x27;s a common courtesy that we don&#x27;t&quot;). But you can&#x27;t stop the fact that we&#x27;re all <i>radiating</i> information to the world. And there&#x27;s nothing invasive in collecting it - you don&#x27;t have to touch me, you just have to stand within my light cone and take a look around.
