Your comment got treated rather harshly, so let me try to explain. The post is on topic for HN because, although the question is a whimsical one, it gratifies intellectual curiosity (please see https://news.ycombinator.com/newsguidelines.html). Whimsical submissions like it have always been welcome here, as long as they're uncorrelated with anything that's appeared recently. (Sometimes people start doing the copycat thing of posting follow-up stories on almost the same topic. Those get old quickly unless they're really interesting, so the bar gets higher superlinearly.)

It isn't just a question of the community upvoting it. Plenty of stories get plenty of upvotes yet still don't belong on HN—e.g. most sensational controversies.

Many HN users value the diversity of the stories that appear here and don't take well to comments that appear to want to narrow the site down. That might be why your question got flamed.

Every post starts out at 0. The community decides who to upvote and downvote. So does it deserve to be on hackernews? Hackernews users decided it does.

It does, but anonymous accounts questioning what belongs on HN and what does not do not.

The users who make up hackernews have voted. It do.
