I got really surprised when I read the “original blog post” because it's less a blog post than is it some bland advertisement to “some online coaching that will make you a 10x engineer”. So when I see the OP qualifying as ”short and well-written, well worth the read“, I suspect all this is just a PR stun to attract attention to Cupać's paid online training program… (and this seems to be working pretty well since it's now on the top of the front page)
