I don't really think that's a sensible comparison--implementation of an algorithm (i.e. implementing Raft) and application of algorithms knowledge to a problem (i.e. a canonical coding interview) are two completely different tasks, no?
I think it's odd that HN is so blasè about the latter, and so afraid of the former. It's like people have put the problem on a pedestal and become irrationally afraid of it. It's easier than much of the other subject matter that the hive mind claims to have mastered without issue, and pretty small in scope.
