Not wrong, but one could frame that as a "cost" that you pay in the space of genealogical problem solving. Having one less constraint makes it easier to adapt to other evolutionary pressures

Agreed, it's just shorthand/abstraction. Just like my for-loop in python doesn't actually mean my computer speaks Python

I omitted some bits from the quote for brevity and HN's faux-quoting sucks, but that's not really the type of "cost" the article is talking about: "maybe they’re suffering from much more subtle neurological effects, like being prone to insomnia or hallucinations or sexual dysfunction. Or maybe they’re just a bit dim."
