I don't think is fanaticism.

It's about easy of use and workflows. Most of the desktop apps and websites don't care about keyboard navigation (and usability) and you have to use the mouse no matter what.

When your main workflow is keyboard based, changing to the mouse and back to keyboard is very disruptive. When you use a tiling window manager such as Sway or i3 this is even more important.

Also, TUI applications go straight to the point, load extremely fast and barely use any computer resources.

When your vision is not very good, the terminal has one big advantage: the same font size and same contrast for everything (I use VT100 mode, so no colors).

I have recently upgraded to a 150-dpi monitor, and now pretty much all graphical programs are unusable, because I cannot even find the menu item to increase the font size without a magnifying glass, and even then most programs do not let you change the UI font size. Terminal for everything is a great remedy for all these troubles.

Context switching and keyboard skills. Part of me wishes I had those skills, but at the moment I still reach for my mouse frequently. I don't have the time or brain plasticity to learn how to terminal only, and there's always tons of setup-while-learning to do.

Just about everything is faster to read, do, and interact with via terminal.

One of the few exceptions would be reading a novel, though :)

For some, I think they reached a state of it being so flexible that other concerns, like proper typesetting in this case, are simply not important. This hasn't happened for me, at least, who tried once or twice to try to use Emacs as a mail client. There was more massive unknown tradeoffs as opposed to just using a dedicated GUI client or webmail, particularly in relation to the type of email people send (heavy HTML emails sent by default from email clients.)

Regardless, I do like a lot of things being in the terminal and tend to reach for that first or Emacs dired even for even basic file manipulation instead of the Dolphin (KDE's file manager) just because of habit. It's just easier in a lot of cases.

> e v e r y t h i n g is much faster on the terminal

GUI means slow and high latency

Terminal means fast and low latency

Its not fanaticism. Its preference. You can use GUI apps if you want, but others just find the terminal more comfortable.

Are there any terminals that can render different fonts for different parts of the ui?
