Most senior could make sense (although I’d like to see a collection of independent guilds coordinated by an LLM “CEO” just to see how it could work—might not be good enough yet, but it’d be an interesting experiment).
Ultimately, I suspect “AI” (although, maybe much more advanced than current LLMs) will be able to do just about any information based task. But in the end only humans can actually be responsible/accountable.
Only thing to add, maybe we have the most senior of seniors verifying the decisions of AI.
