1) The document discusses the future of continuous delivery, highlighting its importance for cloud-native services, healthcare, and manufacturing. 2) It reviews the history and evolution of continuous delivery, from its origins to its use in cloud-native applications today. Lessons from cloud-native approaches like transparent operations and automation can be applied in other domains. 3) The production environment of 2030 is predicted to involve approaches like "factory as code" with software-defined factories and highly instrumented and automated systems. Continuous delivery and operability will be crucial to developing and maintaining these complex, safety-critical systems.

Basically Toyota has created "Factory as Code".
They call it "Flexibly Configurable Assembly Lines" -
tapeless guided vehicles, solar & wireless rail-less
transport equipment, wireless andon, assembly
equipment is floor based vs old overhead.
