Grumpy old-ish fart, here. These fancy, ricer terminal things, whether it be emojis in your $PS1, clueless reinventions of TurboVision, or OpenGL crunch effects when I press a key, but all ultimately emulating a teletypewriter machine from the 1940s are just extremely cringy to me. Emulating one on top of a browser stack probably takes the cake though.

We had document/text oriented interfaces in the 80s that were also graphical like in Genera, a lisp machine OS https://en.wikipedia.org/wiki/Genera_(operating_system) This should have been the direction we should have followed. Instead, Unix and X Window systems - the most expensive way to run a teletypewriter - some how won out in the economics of things.

I hope the current approach of fancy terminal apps is just a local minimum we can kick ourselves out of in he long term.
