It&#x27;s also worth considering that Joyent is likely feeling threatened by Docker picking up unikernel wonks, because until now Joyent has been able to keep Docker in a &quot;containerization and deployment&quot; box, competing on other things in SmartOS and other parts of their stack. Now Docker is pretty plainly coming for more of their pie (with the winds of &quot;hot new valley thing&quot; behind them, which Joyent distinctly lacks), and this wouldn&#x27;t be the first time Cantrill has blogged out of feeling threatened or angry.<p>I don&#x27;t agree with minimizing arguments based upon personal opinions of the author. Please don&#x27;t interpret my comment that way. I&#x27;m just pointing out context, which is worth considering when evaluating the arguments.
