I think some elements of the "I'm an engineer, this is numbers, I can do numbers, I can do this"-itis seems to flair up quite a lot on HN in particular because it self-selects a certain type of person.

I do like it here but it really makes me laugh sometimes.

> The CFR of COVID is less than 0.5

The CFR of COVID—and everything else that might be require ICU care—goes way up when hospitals are overwhelmed because the infection rate isn't controlled. CFR isn't a constant.

At my college, it was a bad year when a dozen students died (which can have a negative effect on the mental health of a surprisingly large # of people). With a 0.5% fatality rate, there'd be hundreds of deaths.
