If humans are right on the line between smart enough and not smart enough, isn’t it an implausible coincidence that’s the case?
There’s always the scary and depressing option that it’s not a coincidence, but the two are correlated. E.g. the “true moral law” is in fact such a catastrophic fitness disadvantage that all biological species can only stop their intelligence development short of discovering it. Else their intelligence switches from being a benefit to being a burden, as they constantly get outcompeted and eventually driven to extinction by their duller but more unscrupulous cousins.
