"There's probably a very big difference between" - that is precisely my point. I have a lot of time playing ms flight sim and so obviously I know how to design airplanes is his argument. Writing "greenfield" applications that no one (comparatively) is using is relatively easy. Creating systems that have four+ 9's availability, integrate with various disparate APIs, don't lose data, and,and etc is where, IMO, the learning is. Once one has this experience, watching this micro services "movement" is, in my mind, related to global warming - like watching someone jump out of a plane with no parachute, smiling.
