> never attribute to malice what can be explained by stupidity, EXCEPT when money is involved

The FAANG corollary:

When you make it a point of pride to only hire the smartest, most elite engineers on the planet, presumption of stupidity no longer applies.

Grueling rounds of leetcode interviews and system architecture questions doesn’t exactly select for either common sense or detailed knowledge of either human nature or even retail.

No one knows how to hang onto a dumb idea like a smart person.

Just because the average person can't prove them wrong by argument doesn't mean their right.
