The discussion revisits unikernels, where an application is also its operating system, and considers how AI relates to their earlier development challenges. Engineers weighing this system architecture may find the historical context useful, though the excerpt gives few implementation details.

Networking and services such as web, DNS and email must be provided as application libraries; Mirage had TCP and HTTPS stacks but little storage.
