Yeah. Any digital file system that would be better would be better IRL too, assuming the physical items had the same properties as digital files. So whatever organization system they come up with should work with paper sheets, music and game discs, etc. as well as digital files. And yet most of the ways organizing physical items sucks is 3-dimensional spatial dimensions, non-repelicability, non-trivial to move around/access/put back, etc. All things digital files have (although files still have a 1-dimensional dimension requirement in file size and probably more volatility.

Haven't heard anything that's better. Especially since the alternative file systems I've heard about seem to be more abstract and don't convert back into hierarchical file systems as easily as hierarchical file systems are able to absorb whatever mushy connections/logic that people seem to partially desire via metatag systems and shortcuts/symlinks.

Like, right now I can sort all my anime via a folder titled "!genre" and then inside it have non-exclusive genres with shortcuts to the anime folders I would consider horror, classic OVAs, want to re-watch, etc. I don't see how having a more abstracted file system makes this any easier or faster, necessarily. The people who don't want to deal with this seem to not want to deal with computers at all and want a Star Trek/AI/etc.-type agent to handle it all for them via voice command or thought command or something. It's not an incompatibility with current computer systems, it's their ignorance or hatred of them in totality.
