People should also stop using terminal emulators. It is pretty silly to base software around ancient printing terminals. Everyone knows for a fact that only tech illiterates use a console instead of a GUI. Since all great devs use a GUI. Just a fact.

Also, people should stop playing 2D games. It is pretty silly to base your entertainment on ancient technology when modern GPUs can render super-complex 3D scenes.

And don't make me start on people who still buy vinyl...

Current GPU's can't compete with my brain 'rendering' a Slash'em/Nethack scene with my pet cat while I kick ass some foes with my Doppleganger Monk full of Wuxia/Dragon Ball/Magical Kung Fu techniques.

Honestly hard to disagree with your first point even though it's sarcasm.

It's still quite easy to end up with a terminal you need to reset your way out of (eg with a misguided cat), not to mention annoying term mismatches when using remix/screen over SSH, across OSes, or (and this is self inflicted) in containers.

Completely disingenuous. Stop the snark.

For UI there exists a straight up superior alternative, which keeps all of the benefits of the old solution. Neovim is just straight up better when used outside of a terminal emulator.

What is true for TUI vs. GUI is not true for CLI vs. GUI (or TUI for that matter) pretending the argument I made applies to the later is just dishonest. You can not replace CLI interfaces adequately by GUI or TUI interfaces, you can totally replace TUI Interfaces by GUI. See neovim as an example. It is superior software when used outside of the terminal.
