They forgot to add 'make it as simple as possible' in the prompt is one possible cause.

On a more serious note using a react-like lib for TUI in the hope you'll share the codebase with the web version is a more likely explanation. Still not the best idea.

React is not that stupid to re-render in a loop at 60fps and instead waits for changes to happen before re-rendering. It even batches changes and stuff.

You don't need React for reactive TUIs - at all. I can understand chosing React for web, but for a TUI it sounds like a really poor idea. And in practice we can see that the claude code TUI is also poor.

So how much more improvements are there for efficiency in the Claude code base if they are using react for a tui, in the rest of the code?

I also wonder about the wasted cycles and just the environmental damage caused by all these wasted cpu time . (Edited added a comma for clarity)
