The whole universe is based on inefficiency. It allows ecosystems to thrive and it builds resilience. Start optimising and past some point (actually quite early in the process) you are sacrificing resilience. Pushing for extremely efficient systems is wrong architecture move. Resiliency of the ecosystem is much more important than efficiency of any part of the system. It translates to digital world as well. Have you noticed how many non-essential services are integrated to operating systems? It is definitely more efficient to have a fitness app included in the os, but over time you lose the whole ecosystem of third party fitness apps. It’s the same as the state. Every service provided by the state (in the name of efficiency) become monopoly over time. And when it stops providing services (and it sure will), it leaves void and barren land. There is nothing to step up. It is good to identify waste, but even lean meat needs fat to be fully digestible.
