i think you are a software guy like me, some process are to dynamic to fully automatize and make excessive division would make the process less resilient and more prone to accidents, container are cool but real container are make of real material, ship problems happens, manufacturer them isn't cheaper or easy and this real physical scale make them expensive to storage.
TL;DR the world isn't kubernetes
That's a great line - the world isn't Kubernetes. Yes, in the real world, things break and problems arise. Things that worked in one context break down in another. In one of the chapters, I talk about the huge amount of maintenance work needed to keep these systems running, 'unsexy' work that never gets mentioned in the founder's keynote. There's often an immense amount of labor, knowledge, and expertise behind the scenes, some of it well paid, much of it precarious and under-paid.
