Honestly think we probably underutilise sound sometimes.

Even just having a hum while an agent is working could alert you when it get stuck.

Or taking your idea further being able to listen to the rate of tokens, or code changes, or thinking.

Sort of like hearing the machinery work, and hearing the differences in different parts of the code base.

Does python sound different than rust or c++ or typescript.

Or some kind of satisfying sounds for code deletions and others for additions. Like Tetris.

A long, long time ago I wrote a tool to beep at various tones as lines were added to a log. It was a background noise I would not notice, except when it was changing because of some unusual activites.

It was very interesting to see the brain filering expected soinds and wake me up (or rather grab my attention) when unexpected ones appeared.
