I think Cantrill is doing a massive favour for those who are pro-Unikernels - he&#x27;s essentially trolling them and will force them to come up with responses to some of the issues he&#x27;s making.<p>Given how invested Joyent is in their current positions, I can see why Unikernels may seem a threat, but none of the things Cantrill has raised as concerns seem insurmountable.
