That's been around a while in various forms. It's still no replacement for synchronously asking follow up questions and being available for decision making.
But that's what a modern AI agent can do, which previous ones couldn't. If a company gives it full access to the project management system, your previous conversations with it, and its prior conversations with the other team members, I believe it can be quite good at follow up and recommendations. I do absolutely see managers giving it some limited decision making (e.g. "Yes, we should split this subtask off into next sprint") very soon.
Yea but that's not quite the same social pressure and implication of urgency; people are more motivated if they know they're talking to a human. That's my impulsive guess, anyway.
