For those who don't want to visit X:

    Most people's mental model of Claude Code is that "it's just a TUI" but it should really be closer to "a small game engine".
    
    For each frame our pipeline constructs a scene graph with React then
    -> layouts elements
    -> rasterizes them to a 2d screen
    -> diffs that against the previous screen
    -> finally uses the diff to generate ANSI sequences to draw
    
    We have a ~16ms frame budget so we have roughly ~5ms to go from the React scene graph to ANSI written.

And that's why it's taking so much CPU and is a pain to use with tmux.

Don't link out to x, its trash

What? Technology has stopped making sense to me. Drawing a UI with React and rasterizing it to ANSI? Are we competing to see what the least appropriate use of React is? Are they really using React to draw a few boxes of text on screen?

I'm just flabbergasted.

Ah, the hell site, no click.
