I think Emacs still does all of this; the argument the author makes is that it is "arcane", it just uses conventions he is not used to. It is however fully self-documented and interactive. For me the best textual interface I've ever used remains Magit in Emacs: https://magit.vc/ I wish more of Emacs was like it. I actually use emacs as my git clients even when I'm using a different IDE for whatever reason.
> it just uses conventions he is not used to ...and everyone else, including everyone who is also using a GUI on Linux - even if they use the GUI version of Emacs.
Also, another user said it has a tutorial when opened which should teach the basics in “10 to 15 min” but I have a feeling I would need 0 minutes to learn the basics of turbo c++.
I get that there are diehard eMacs and vim fans and honestly I’m happy for them. But at the end of the day scientifically speaking ease of use is not JUST down to familiarity alone. You can objectively measure this stuff and some things are just harder to use than others even with preloaded info.
