I know that article, it&#x27;s excellent. And I like Paul Graham&#x27;s point of view, usually. But that article addresses (and will ever only address) the &quot;elite&quot;. Like QUEL, which didn&#x27;t make it. SQL did.<p>This doesn&#x27;t have too much to do with innovation. It has everything to do with product-market-fit. SQL is the technology for the masses. QUEL (or something else more recent, very lean and sophisticated) is the technology for the elite. But why doesn&#x27;t the &quot;elite thing&quot; go mainstream? Wrong product-market-fit.
