After several months with their top engineers and state-of-the-art AI on the job, Anthropic managed to "reduce flickering by 85%" on their TUI Claude Code client, which is built in fucking React and rendered by drawing the entire chat conversation each time (hence the flicker). I think they've since eliminated it completely by slapping some double-buffering around it (since "our client is actually a real-time game engine" after all). Meanwhile for decades Emacs and Vim have had an optimizer built into their display cores that solves for the minimum set of terminal escape commands it takes to transform the screen from a given old state to a desired new state.

You will forgive me when, between muted snickers, I express considerable doubt that Anthropic will be able to bring its AI to a point of "self-improving" any time soon.
