I was not the one claiming security is binary. The opposite of that (I happen to work in security)... people just casually claiming that 100% of the vulnerabilities in Chromium are due to memory unsafety are implicitly claiming that none of them were logic bugs and what follows is that had the same code been written in Java, Rust, even Python for that matter, none of those vulnerabilities would've been possible - which means there would be no vulnerabilities at all!? I would expect people commenting here to have basic understanding of propositional logic.
