I was a bit disappointed.  From the headline I thought it was an argument about why the ad-fueled internet is economically unstastainable.  Instead Brin is mainly repeating the &quot;moral&quot; case against it while making some (reasonable) suggestions about why micropayments are not so impossible after all.<p>The later point might be right, but only likely to be tested if there is an advertising bust.   At least Brin links to this (<a href="http:&#x2F;&#x2F;idlewords.com&#x2F;2015&#x2F;11&#x2F;the_advertising_bubble.htm" rel="nofollow">http:&#x2F;&#x2F;idlewords.com&#x2F;2015&#x2F;11&#x2F;the_advertising_bubble.htm</a>).
