Sorry mate I think you may have missed the joke?
I wouldn't say ripped Aryan men is the "main topic" of the joke. The subject of the joke is very clearly the "who cares how it was coded" crowd (referencing those permissive of LLMs). Along with the implication that their "idea" of an ideal human is counter to the fact that many of the best technical professionals (whome they could only aspire to imitate) are often, distinctly, not aligned with that perceived ideal.
See, humor is all about the juxtaposition of novel subjects.
