I agree with most everything else you said, but would slightly push back on that. I actually quite like the idea of non-hierarchical blob storage searchable via arbitrary indexed metadata, as well as the idea of content-addressable storage (e.g. with magnet links). While folders are an elegant abstraction, I really feel that we shouldn't be beholden to it.
