Outside Linux, on Windows/Mac, plenty of non developers much prefer the "desktop UI" experience over CLI. Some can't work with CLIs at all.
Even with Linux, there are more people -- including many non software engineers -- that are installing Linux on their home computers and may be interested in this.
Bear in mind that HN users don't remotely resemble the general population, or even employees at a tech company -- there are lots of people in finance, business, legal etc who could potentially benefit from this.
I’m a developer, daily driving Linux, and prefer GUI apps. Would’ve used Sublime Text if clangd plugin worked. Hence stuck with Emacs. Open Code GUI sucks compared to their TUI though.
