I think this definitely reads way worse than it is. I grew up in small town Iowa, and most adults from my town would not handle upscale and fancy well. It would be like if I went to Buckingham and was expected to know proper etiquette.
This definitely has asshole phrasing, and probably is just a shitty person, but I can empathize with the core idea.
Technically, it is a skill issue though, but requires borderline perfection to achieve safe code. It’s still a bad argument and detracts from progress in an area where it’s sorely needed. Correct me if I’m wrong, but my understanding is that everything unsafe is because the logic used left something exposed where rust has rules in the language the prevents those had coding practices. C is inherently unsafe, it just doesn’t have built in safe guards to keep the dev from using it wrong.
