I'm not sure HN is representative of anything, especially if you only look at what's upvoted. If I had to guess, I'd say that this sentiment is posted by people with 10 years of experience who feel like they should be talking about something else during interviews, but that it's being upvoted by college students or recent grads (no matter what you're asked to learn, a large fraction of the group will be frustrated by it)
