I played with it recently. The interactive part is limited at the moment, but I really like the idea of having operations like sorting and filtering separate from the tools which produce the data. Having these things consistent and available everywhere is a huge cognitive win. I can finally sort and filter `ls` output without having to read the man page. :) "Querying" data feels a lot like SQL in that respect.
This isn't the way I'd sort ls output by date or whatever field. I'd use `ls -l --sort=date` which I guess is what the GP meant with having every tool do their own sorting by field.
I also like that nushell's table oriented approach displays the column names, and you just use those names for the `sort` command or `where` command etc.
