I will take your word for it that > The question in the post is "Why is the universe this way and not another way?" not "Why do we choose to use complex numbers in our description of the universe?" but why then does he so prominently raise this question at the beginning, answer it later, and title his post "why are amplitudes complex?". I must be really out of the loop. Did I really get the subject of this post so badly wrong? Sorry about that. Is this not a very confusing way to go about discussing why the universe is this way and not another?
