Just bash, the command-line tools one uses from bash, LaTeX, and emacs/vim. I think git will stick around for decades even though its predecessors didn't.
My machines pretty much run Emacs, LaTeX, and Firefox, and everything else is largely window-dressing[0]. (I end up doing most of my command-line stuff from eshell inside of Emacs these days.)
[0] Well, a WM/DE of course, either Stumpwm or Plasma. And pdfpc[1] is really pretty fantastic for showing "Beamer" (pdf) slides. And syncthing for sync'ing between machines.
