Ask HN: File System Design in 2024?

I have been cooped up for this long winter and probably need to get out, but I have been having a lot of thoughts about file systems and the future of storing data.

This leads me to ask (since I haven't experimented with file system design since 2006?) where are there file system design resources in 2024?

(I am aware of the classic "Practical File System Design with the Be File System by Dominic Giampaolo)

Edit: I also feel like some of my thoughts have been coming after the recent update from Hans Reiser.)
