Applied research and engineering notes from Coex Systems.https://coexsystems.com/https://coexsystems.com/research/what-if-containers-didnt-have-to-share-the-same-kernel/https://coexsystems.com/research/what-if-containers-didnt-have-to-share-the-same-kernel/Autonomous development workloads sit awkwardly between containers and virtual machines. Kernel choice may need to become a scheduling decision rather than a property of the physical host.

Conversational infrastructure needs a boundary between interpretation and execution.

Revisiting that assumption separates public presence from mail ownership.

Separating the two is the point.

Reversing that order changes what adoption actually costs.

Separating capacity from performance changes that.
