In these discussions, people tend to forget the unsexy problem: coordinating work between humans. The reason an architecture is chosen is often purely a result of Conway's law. Just like the code organized on disk is often purely a result of how your language or build tool prefers you organize your code. Subconscious bias controls a lot of what we do, so designing systems partly requires an understanding of psychology and management techniques. If that sounds crazy, just ask W.E. Deming. The reason Toyota came up with TPS was not because they were geniuses, or the discovery of some "magical architecture". They just focused on how to always be improving quality and efficiency - which at first makes no sense at all, and sounds exactly like premature optimization. But the proof is in the pudding.
