For a layman the abstract sounds like a computer-generated hoax.

You could say that about any field that one is unfamiliar with. Heck, the most basic art concepts could seem like so to a blind man. Mathematicians have worked for ages on simplifying the concepts so every term is there because it helps a trained mathematician understand what is going on.

It seems genuine, or at least more sophisticated than computer-generated abstracts usually are. It seems to repeatedly mention the same concepts which is something usually lacking in computer-generated abstracts, though it does mix seemingly tenuously related topics.

I have no idea what any of it means though.

The abstract, although it's also far beyond me, actually sounds even more impressive than the article lets on.
