As was pointed out on Twitter, this paper, while amusing, should not have made it through arXiv moderation, as the arXiv specifically prohibits "joke" submissions in favor of papers which are, at least ostensibly, serious scientific contributions.
To me, this undermines the credibility of the other content since the "joke" tries to portray as genuine by being published on arxiv. It sort of dilutes to credibility of others.
Arxiv isn’t supposed to be a badge of credibility. It’s literally the place any academic can dump a paper to have it stored free forever. Many academic papers that never make it into journals are stored there. From their homepage they say:
> Materials on this site are not peer-reviewed by arXiv
That said, they shouldn’t actively accept joke papers of course.
>Animal welfare and rights are also crucial for creating a trustworthy
and reliable Proof-of-Steak platform. We go beyond traditional
animal welfare requirements by affording our animals all of the
rights granted to “natural persons” under the GDPR. To comply with
GDPR Article 25 on data protection by design, we use differential
privacy and distributed analytics [2] to obfuscate the identity of
any given Kobe cow so as to prevent them from being singled out.
