Fun. I must admit I don't really know who this is for, but it seems fun.

It's for people that want to use the Windows Terminal to edit files. The old `edit` command has been unsupported on Windows since 2006, so there was no Microsoft-provided editor that could be used in the command line since then.

It's impressive to see how fast this editor is. https://github.com/microsoft/edit/pull/408

Is... this a meaningful benchmark?

Who's editing files big enough to benefit from 120GBps throughput in any meaningful way on the regular using an interactive editor rather than just pushing it through a script/tool/throwing it into ETL depending on the size and nature of the data?

As a specific benchmark, no. But that wasn't the point of linking to the PR. Although the command looks like a basic editor, it is surprisingly featureful.

Fuzzy search, regular expression find & replace.

I wonder how much work is going to continue going into the new command? Will it get syntax highlighting (someone has already forked it and added Python syntax highlighting: https://github.com/gurneesh9/scriptly) and language server support? :)

Right, these are more useful features, IMO, than the ability to rip through 125GB of data every second. I can live without that, but syntax highlighting's a critical feature, and for some languages LSP support is a really big nice-to-have. I think both of those are, in this day and age, really legitimate first-class/built-in features. So are fuzzy searching and PCRE find&replace.

Add on a well-built plugin API, and this will be nominally competitive with the likes of vim and emacs.
