I mean it was an example I chose because the name recognition in HN. I would doubt Knuth would publish garbage. Then again, how would you know? If you've never been in academia it's understandable to think that way. But if you have, you realize the immense pressure, self-doubt, and scrutiny you'd have even making a bold, well researched, attempt to prove someone like knuth wrong even if it was obvious he was. I recall several instances in mathematics where this happened and it bordered on starting a war between mathematicians.
