You ever see a dog that’s got its leash tangled the long way round a table leg, and it just cannot grasp what the problem is or how to fix it? It can see all the components laid out in front of it, but it’s never going to make the connection.
Obviously some dog breeds are smarter than others, ditto individual dogs - but you get the concept.
Is there an equivalent for humans? What ridiculously simple concept would have aliens facetentacling as they see us stumble around and utterly fail to reason about it?
You’re right, and I suppose I was half-thinking along the lines of “we have all the pieces to solve this, but we don’t because we’re frozen in place by greed” instead of “this is something we could do with infrastructure today”. If everyone could collectively let go and re-distribute wealth and materials efficiently everyone would be much better off for it, but instead we’re stuck in some game theory hell where the optimal personal choice results in one of the worst outcomes.
