That's fair. It's also the case that to some extent HN's article titles serve the same purpose as that one line description in a speed dating event. They're ice breakers, everybody has the same prompt and then writes about that, and even if they did read the article which I agree often they don't, they come at it from a different angle. I feel similarly to the article author, it is trivially true that we could express anything in all the general purpose languages, that's what general purpose even means, but I find for Computer Languages the Weak Sapir-Whorf Hypothesis checks out pretty well. The language changes how you think about the problem.
