These sorts of comments frustrate me. You seem to take objection to drill being described as "aimless", but clearly the author is using that term to describe his perception at the time before going on to show how it wasn't aimless at all. This makes me think you didn't try to understand what was being said before attacking it. I once heard the concept of an "Iron Man Argument", being the opposite of a Straw Man. Let's take the most charitable and coherent interpretation of an argument that is presented to us and try to poke holes in that. Then we will both be better for it. Maybe this guy is dead wrong. But defeating arguments he never made will not determine that. Sorry to be a grump. It just frustrated me that this was the top comment.
