<i>In 15 years when the search engine have failed to evolve because Google is a monopoly and has no incentive to keep improving it, you may have a different perspective.</i><p>LOL, Wut?<p>I don&#x27;t think you appreciate what it takes to maintain and improve a search engine these days.  For example...<p>Remember when link farms were big? They were doing this to boost their score for the existing PageRank algorithm.  All search engines had to detect this, to determine in an automated fashion (because the web is waaaay too big) when to ignore that crap.<p>And in a related issue.... spam.  Fifteen years ago, guys like me were trying to fight it using regular expressions to filter our inbox (Spamassassin).  It was a losing battle, even then.  We&#x27;ve needed the very best machine learning to try to keep our heads above water.  The spammers are constantly improving what they&#x27;re doing too.<p>The search engine looks the same (simple one-line text box), but the infrastructure behind it has vastly changed, and continues to rapidly evolve.   Go read the Spanner and F1 papers... that stuff certainly didn&#x27;t exist at all when Google started.
