> With GPU terminal emulators

It seems like something like inline postscript rendering makes sense for things in a terminal - it's text, vector based, versatile.

Then Markdown or man/mdoc are easily rendered.

Not sure what you meant with gpu terminal emulator but i use consolemd https://github.com/kneufeld/consolemd to render markdown for terminal and it works really well.. i even built my cheatsheet site with it using simple bashscript (eg: curl https://ch.ebfe.pw/nix/xargs)
