There was a great thread going when this article was posted a few days ago, which was strangled by inappropriate flags. I'm going to move those comments here to give them a second chance.

Flaggers: please don't flag submissions that don't break the site guidelines! This article is obviously on-topic (see https://news.ycombinator.com/newsguidelines.html). If it isn't your cup of tea, there are plenty of other things to read. If you run out, the 'past' link at the top will take you to arbitrary amounts of reading material that you missed.
