Never attribute to stupidity what is adequately explained by opportunity cost
I don't get the use of the terminology here.<p>Opportunity cost is the cost associated by not reaping the benefits of an alternative not being picked. This is a cost from the perspective of the party making the choice.<p>So in this story, 'opportunity cost' is not an <i>explanation</i> why something didn't happen. It is a side effect of something not happening.<p>You could say the real opportunity cost in this story is the startup teams having a bunch of unhappy users. The <i>explanation</i> for the missing features is simply: they did something else.<p>So better: "Never attribute to stupidity what is adequately explained by prioritisation"
