The story didn't change. But there are as many examples of inefficiently effective natural methods as there are efficiently effective natural methods. Like in the evolution of plant life. When there was a surge of diversity and plants started using insects and animals to help them pollinate, because it was far more efficient than spewing pollen to the wind. Look at it this way.
Nobody likes efficiency.
But precision is efficient. I love precision and I think you love precision. But I'm talking about decided what to execute. It's like Fred Astaire and Ginger Rogers. Their execution is magnificent.
