I have updated the comment with the explicit problems. I still believe that the link post has near zero information as it provides no actual facts to back up any statement. All it says is "xmpp exists so it should keep existing because [hand wave]", with a dash of pseudo-biology thrown in.

I feel I need to be clear here: I understand that simply saying "this is nonsense" to an arbitrary post is not reasonable, but it is also unreasonable to require a detailed teardown of posts that are nothing but nonsense. Requiring such work is a bedrock of scammers, pseudo-science, spammers, etc as it makes it harder to stop them: if every response has to be well thought out and cited eventually people give up, and the posts go uncontended, which gives them the appearance of relevance or legitimacy.

This post is a nonsense article. It contains no information, it makes no actual claims beyond "we have xmpp so we should continue to have xmpp", it is far too long for the actual content, and the content that is there is largely hand waves references to a badly made and incorrect pseudo-scientific analogy.

This is the kind of post that does deserve a dismissive "this is nonsense" response.
