We could do so much better. >Not only do I not dislike type theory vehemently, I really like some of its uses (like linear types; don't believe me? I praised them in a recent talk: [video I'm not too fond of deductive proofs as a software verification method because so far it manages to scale worse than other formal methods (that don't scale that well, either). What I strongly dislike is: > >1. Fetishization of certain formalisms, particularly combined with a rather limited understanding of said formalisms or formal syst…
