From TFA: &quot;<i>At best, unikernels amount to security theater, and at worst, a security nightmare.</i>&quot;<p>As a security engineer, that&#x27;s a good one sentence summary from my point of view of unikernels, since, forever.<p>I think the reason why unikernels are being developed is due mostly to ignorance, and if any of them is successful, it will morph into an OS that is closer to Mesos, Singularity, or even Plan9. That&#x27;s faster, safer, more logical, etc.
