Thank you for this comment and many others in this thread. I feel I've been converted to the YYYY-MM-DD structure. Because it's in order of specificity. It feels like it saves time and potentially compute.
However, I think a big problem with this is the way people say dates colloquially. Such as, March 24th 2019. Or even the 24th of March, 2019.
I can't imagine saying to someone, oh can you come over to my party, it's 2024 September 5th.
In many ways digital is designed to be a facsimile of analog. So sometimes what "makes sense" to people hyper fixated on the topic are simply not amenable to real society.
