As someone who has used and contributed to Julia, I find Yuri Vishnevsky's arguments about correctness totally fatal [0]. And Yuri's examples are not obscure, they are totally realistic scenarios where Julia silently returns wrong results in ways that may be hard to detect. I do mostly scientific computing, and the idea that I might have to retract a paper because of a bug in the programming language is intolerable. It doesn't matter how beautiful and fun to write and develop the language is if it can't be trusted to return correct results.
