I'm with you on this one. "Terminals are too slow to support lots of text so we had to change this feature in unpopular ways" is just not a plausible reason, as terminals have been able to dump ~1Mb per second for decades.
The real problem is their ridiculous "React rendering in the terminal" UI.

They did. And the result was a React render loop that takes 16ms to output a hundred characters to screen and tells them it will take a year to rewrite: https://x.com/trq212/status/2014051501786931427

What's extra funny is that curses diffs a virtual "current screen" to "new screen" to produce the control codes that are used to update the display. Ancient VDOM technology, and plenty fast enough.
Heck, simply handle the scrolling yourself a la tmux/screen and only update the output at most every 4ms?
It's so trivial, can't you ask your fancy LLM to do it for you? Or you guys lost the plot at his point and forgot the most basics of writing non pessimized code.
