But why would I want to suck through my computation through a VT220 straw when I don’t have to?
You don’t have to.
But, sometimes, you want to. In my case, I search for some kind of “minimum, Zen-like environment” that is enough to do my work, and the advices from that text help me achieve that.
Or, as the case of the author, you don’t (want to) have a hardware that follows the requirements of resource-inneficient applications that do only the bare minimum work that simpler machines did incredibly well decades ago.
But you do not have to stick to vt220, and can use the default one (pccon0) as well, and still enjoy the recommendations of the essay. 🙃
This is an extensive manual on how to work only on console (i.e., not on graphica, or X, environment).
The author goes on the different *NIX systems, explains how console works, as well as they presents several alternatives for common graphical applications for the console.
I do use the console exclusively when working with remote systems as the author points out. But only because the machine ssh from has a graphical environment. I also love tmux, because iTerm2 has fantastic tmux integration.
That said, this article is mind bogglingly thorough and a fantastic read. I expected probably 1/10th of the detail here.
