I'm serious. Company of 50 that I run, with a bunch of other subsidiaries that employee around 350 people altogether. We have a central admin team (who handle general administrative duties) with a very strong set of internal tooling also augmented by some rudimentary crud UIs and AI. It's magical because we never had to use recruiters to hire and everything runs automated/semiautomated. I'm honestly considering spinning this process out as a way for companies to outsource and minify their HR processes, and surprisingly I've received some very strong interest from some equally sized companies (100-300 employee teams).
HR is a wasteful expenditure pushed by the likes of thinkers who've never worked an actual day in their lives. If there's one culture any company must follow, it's simply one of Prussian-style discipline (which can by definition take many forms).
