&gt; Now that&#x27;s more depressing than global annihilation.<p>Fair point.  But I honestly wonder if it&#x27;s not true, or close to true.  I mean, people have been talking about the &quot;end of science&quot; for a while now, even though we know we&#x27;re not quite literally at &quot;the end&quot;.  But let&#x27;s say that we unify relativity &#x2F; gravity &#x2F; QM in the next 100 years or so, and identify the exact nature of dark energy &#x2F; dark matter.   Presumably that would represent knowing close to everything about the physical world that its possible to know.  And if we can discover that, it does lead you to wonder &quot;what else would more intelligence represent&quot;?<p>Of course, maybe we&#x27;re WAY more than 100 years away from those things.  Or maybe we&#x27;ll never get there.  Or maybe if we do, it doesn&#x27;t mean anything vis-a-vis the limits of intelligence.  I&#x27;m just thinking out loud here, this isn&#x27;t an argument that I&#x27;ve put a lot of time into developing...
