Sadly, it is a detachment from reality that is entirely normal, even typical. In all walks of life.
What I still find surprising, even though normal, is how technical people can push actual facts and evidence right out of their world view.
Sure, 70% of the bugs in C++ code bases are memory rated according to multiple sources. So let me aggressively and confidently berate this idiot that says the Rust compiler is doing something useful.
You do not have to use either language to see how idiotic this is. Even if you accept that this guy has “the skill” to make compiler help redundant, he has no point at all unless he thinks that “typical” C++ users have that same level of skill. And, provably and trivially researched—they do not. Being this wrong makes him, as self-evidenced, incompetent by definition.
All he proves in the end is that he is angry (and I guess not a fan of Rust).
“Angry and incompetent” is sadly a much more common trope than the ones he tires off.
