To me delegation requires the full cycle of agency, with the awareness that I probably shouldn't be interrupted shortly after delegating. I delegated so I can have space from the task and so babysitting it really doesn't suit my needs. I want the task done, but some time in the future.

From my coworkers I want to be able to say, here's the ticket, you got this? And they take the ticket all the way or PR, interacting with clients, collecting more information etc.

I do somewhat think an LLM could handle client comms for simple extra requirements gathering on already well defined tasks. But I wouldn't trust my business relationships to it, so I would never do that.
