Nature likes to overinsure itself. Layers of redundancy are the central risk management property of natural systems. We humans have two kidneys (this may even include accountants), extra spare parts, and extra capacity in many, many things (say, lungs, neural system, arterial apparatus), while human design tends to be spare and inversely redundant, so to speak — we have a historical track record of engaging in debt, which is the opposite of redundancy (fifty thousand in extra cash in the bank or, better, under the mattress, is redundancy; owing the bank an equivalent amount, that is, debt, is the opposite of redundancy). Redundancy is ambiguous because it seems like a waste if nothing unusual happens. Except that something unusual happens — usually.

To be a real Human, one needs intelligence, courage, tenacity, curiosity, and a strong sense of justice. Remove any one of the five and you end up with the equivalent of a lemon. Remove the sense of justice and you end up with a monster.

In any profession, 90% of people are clueless but work by situational imitation, narrow mimicry & semi-conscious role-playing. Except social "science" and journalism where it is 99% and 100%, respectively.
