<i>His argument is basically even if unikernels are faster and even if they are just as secure, they are still operationally broken because you cannot debug them.</i><p>I personally agree that this would be a stronger argument, but unfortunately it&#x27;s not the argument he&#x27;s making.  Instead, he&#x27;s &quot;pleading in the alternative&quot;, which is less logical, but can in some situations can be more effective.  The classic example is from a legendary defense lawyer nicknamed &quot;Racehorse&quot; Haynes:<p>“Say you sue me because you say my dog bit you,” he told the audience. “Well, now this is my defense: My dog doesn’t bite. And second, in the alternative, my dog was tied up that night. And third, I don’t believe you really got bit.”  His final defense, he said, would be: “I don’t have a dog.”<p>It maps excellently:  &quot;As everyone knows, unikernels never have a performance advantage.  And even when they are faster, they are always terribly insecure.  And even after people solve the security nightmare, they&#x27;re still impossible to debug.  But what&#x27;s the point in spending time talking about something that doesn&#x27;t even exist!&quot;<p><a href="http:&#x2F;&#x2F;www.abajournal.com&#x2F;magazine&#x2F;article&#x2F;richard_racehorse_haynes" rel="nofollow">http:&#x2F;&#x2F;www.abajournal.com&#x2F;magazine&#x2F;article&#x2F;richard_racehorse...</a>
