I think most people are unfamiliar with Erlang&#x2F;OTP. Even if I converted my entire team over, I don&#x27;t know how I&#x27;d hire new people without developing strong internal training.<p>Perhaps that means the real argument is &quot;Unikernels are unfit for production for people who aren&#x27;t comfortable with the Erlang&#x2F;OTP way of doing things.&quot; Yes, this isn&#x27;t a technical argument, but—most people, most customers, don&#x27;t even see SmartOS + Linux emulation as suitable for production (and I imagine the author knows that), not for any technical reason but just for unfamiliarity. And that&#x27;s still a UNIX working in UNIXy ways.
