It's hard to convince people but, Emacs is simple. Have you tried showing your grandmother how to use a computer? Emacs has it's own way a little, but it's a simple way. So long as you don't commit to it before you're comfortable with it, and so long as you don't install packages except magit, Emacs won't come at a cost.
Also can we all agree that tmux nvim and mutt don't quite follow the Unix philosophy? Compared to Emacs, one could say Emacs is closer to the Unix philosophy (until you bloat it)
I think I should at least say what my intent was, I thought that what I say in the video is actually worth sharing. I wanted to be more honest and transparent with the title. The upvote rate right now is 57% and I bet it's because of the title (I can only guess, really).
