I think the argument he&#x27;s making isn&#x27;t that it&#x27;s perfect but instead that this logic doesn&#x27;t hold. Old techniques are not inherently bad. They&#x27;re only bad if we actually did discover something new in the meantime. In this case I think we have learned since then, but the article doesn&#x27;t say that; it just says the old stuff is old and thus bad.
