While reading this I've checked the URL (more than once) to be sure I'm really reading a Nature article. I've checked even the TLS certificate of the site after some while. It has a working DOI, it's form Nature. But it could be something written by an Anon on 4Chan actually! Still not sure what this is, and why it's in Nature. Do they occasionally publish jokes?
