> If anything, it takes years for you to realize design flaws in components of the earliest-developed systems. This is more a symptom of the lack of engineering that occurs in this industry than it is an indication of deep technical knowledge gained over years of study. I'd agree with what you say if I thought there were anything like engineering happening. I've worked on code bases and systems that are quite large. I never saw the learning you suggest. I saw lots of fighting the last battle and the accumulation of years of poor engineering decisions, usually by people who had been a lead for years.
