There's much here I agree with -- and especially with the general lesson of "don't get too hung up on principles," but at one point the article speaks of "1980s entity modelling," in a denigrating way, as if methods of formalisation age. It's like saying that doing logic-style type-level programming or SQL is "1970s logic modelling", and using high-order functions combinators is "1950s functional modelling." Many of the interesting ideas in programming languages from the 1980s haven't yet come of age, let alone grown outdated. Also, it is true that there's much we learn over the years, but also much we forget and reinvent.
