I read the linked info and the comments asking why this was upvoted and it's a good question. The liked answer feels a lot like a text version of a TikTok video. It's an interesting fact that takes very little time to read and makes us feel that we've learned something about a interesting topic outside of our expertise. A TikTok example is a video about a 'little known' fact of quantum mechanics. The linked info gives us the same type of satisfaction we would get from a TikTok, but is on Hacker News because it's presented in a more 'legitimate' way.
