as long as you introduce plans you introduce a push to optimize for cost vs quality. that is what burnt cursor before CC and Codex. They now will be too. Then one day everything will be remote in OAI and Anthropic server. and there won't be a way to tell what is happening behind. Claude Code is already at this level. Showing stuff like "Improvising..." while hiding COT and adding a bunch of features as quick as they can.
