That's the thing though. Martin says that, but then you watch a company scale to billions of people ignoring all of his advice. So the question is - does Martin actually have quantitative proof that what he is saying is correct, or is he just selling wishful thinking? The field of software engineering as an academic discipline is the least understood of the computer science subfields because it's qualitative not quantitative field. Of course scaling to billions of users only proves that it can be done without quality, not that they could have done it better with quality software.
