My guess it's the perfect HN bait. Starts with a meaningful factoid. Makes grand unhinged claims. Then starts rambling about everything under the sun.

If you had a preconceived topic you care about: this blog post gives you every imaginable opening. Free of any substance which might define a direction for discussion.

I think this topic is on a lot of peoples' minds, and it would be nice to get a discussion thread going about it with a quality article at the focal point instead of this completely uninformed one.
