Sadly there's very little value in reading this article, insofar as it contains no useful insights or lessons but rather is simply an exercise in throwing stones at someone's life-work, and, near as I can tell, it comes from out of left field.

Mostly this article makes me feel bad for its author. He must have spent a non-trivial amount of time writing this piece, and it serves no end. I suppose I just can't fathom why it made him feel good to write it.
