This is, of course, an argument against a strawman. I wish the author had not mentioned certain folks by name, because the analysis is interesting on its own, and makes some good points about apparent simplicity. However, by mentioning a specific person, and then restating that person's opinion poorly, it does a disservice to the material, and basically it just devolves the whole thing.

My understanding of Jon Blow's argument is not that he is against certain classes of "safe" languages, or even formal verification. It is that software, self-evidently, does not work well -- or at least not as well as it should. And a big reason for that is indeed layers of unnecessary complexity that allow people to pretend they are being thoughtful, but serve no useful purpose in the end. The meta-reason being that there is a distinct lack of care in the industry -- that the kind of meticulousness one would associate with something like formal verification (or more visibly, UI design and performance) isn't present in most software. It is, in fact, this kind of care and dedication that he is arguing for.

His language is an attempt to express that. That said, I'm not so sure it will be successful at it. I have some reservations that are sort of similar to the authors of this piece -- but I do appreciate how it makes an attempt, and I think is successful in certain parts, that I hope others borrow from (and I think some already have).
