Looks like we understand it enough to say it's all a big ball of mud[1], at least based on that SO comment. Or are you saying that the comment is wrong? And yes, the effect is more complex than cloudflare. Then again, it is a ~6Gb (~0.85GB) executable blob[2]; this doesn't include the training sets and it took a bit to get there. Who knows, if cloudflare spent 4.5 billion years and a whole planet of resources on their next version, the result might have exquisite UX too (plus an ability to write tangental HN comments, and many more).
