What if your guess is wrong though? What if running a planet where even the smart people are this bad at thinking is actually a gigantic risk?

Take climate change for example: have you seen any signs in these forum discussions of anyone with any novel thinking or even curiosity substantially beyond some variation of "trust the science/experts + democracy" on the matter? What if simplistic, faith based thinking like that is 50% underpowered, or even more?

And climate change is just one problem.

> you both made valid points

I'm not one of the two people who had previously made points (though HN's interface does not make it easy to notice that). Regardless - prompting someone to support or extrapolate on an otherwise-unsubstantiated claim is perfectly reasonable (though I concede I was a little snarkier than I could have been).
