I assume the quote is referring to libghostty. In which case a lot of different tools like vs code, Emacs, Gvim, Intellij and other IDEs, even web consoles on stuff like Azure essentially use and reimplement the same core, the idea behind libghostty is to replace those with a common component where long term development can better support the needs of all terminals.

In terms of ghostty itself its just a highly competent use of libghostty, Mitchell’s message above about it being a tech demo is tongue and cheek, but its not far off from the truth. It is just a really solid no bells and whistles, bar excellent execution, terminal emulator that uses libghostty.
