Perhaps, as you suggest, attracting more talent is one benefit of using an FP-oriented language for their codebase. It would have been nice to see this claim evaluated in the context of a cost-benefit analysis including the costs. This article, which claims that OCaml provides a &quot;competitive advantage,&quot; doesn&#x27;t provide that. Thus I don&#x27;t believe it is a useful source of information for evaluating the merits of OCaml in particular, or FP in general, in a production environment.
