I think the long term idea is that AI becomes continuous in the sense that it behaves like a regular employee, not something you have to prompt. So at a mid sized company say 100 "entities", the CEO has directors still, they have managers, but the managers are managing AI agents not humans.

But I don't think that's how it plays out. I think you still need to imbue talent, skills and direction into these tools and I don't see management, who did not have the skills initially, being able to do that task across multiple business aspects and agents simultaneously.

I think for now and perhaps until/if AGI, the sweet spot is having skilled individuals with experience using the tools to known good results. You still can't really delegate to the tools, you have to work with them. The benefit to management that a human has is they can delegate to a human, even when they completely lack the skillset they are delegating.
