this is cool but it's fuse.. which is not so cool.
these days i reach for jq.. I've recently became interested in duckdb too.
Using a tool that is specialized for the format is usually more ideal than a generic one treating everything as files.
There is a lot in JSON that can't be represented in a flexible way as files and directories. For instance, what if a key has "/" in it.. What happens to lists and their order when you re-serialize How are hashes represented.. how can you tell if a parent is a object or a list.. inserting a item into a list is a ton of error prone renames.. the list goes on
