This is a wonderful article.
One nitpick: the practice of "chaos engines" is not how one ensures that one's systems are reliable. Chaos engineering is something that one does _last_ - it is a very advanced practice that you only use if you have very thorough reliability practices in place (failure mode testing). If you don't have those (and most companies do not), then chaos engineering is very inadvisable.
Also, I would discourage people from viewing these changes as "advancement". In fact, many of these things were practiced by Henry Ford. Humans are not innovating in how they behave. Rather, we continuously reinvent ideas and mix them in new combinations, and add new narratives, models, and interpretations, and call it "new".
