I am not dismissive towards Coq (how can anyone be?), and my advice is neither less solicited nor less relevant than many other HN comments.<p>But you are right that I sometimes try to correct what I see as a (strange) imbalance here on HN (which reflects neither the prevailing opinions in academia nor in the industry) regarding PFP and type theory. People unfamiliar with the topic might get the impression that PFP+type-theory is either the only or the most prevalent technique for software verification (or software correctness in general), while neither is the case. In exchange, I get to be the lucky target of various ad hominem attacks, so I guess I&#x27;ve earned my right to speak up :)
