Does an AI Daily Briefing Make the Morning Quieter?

Meta says its new AI can read connected calendars and email, flag conflicts, and send a recurring daily briefing. I’d test it against the morning it replaces, not an empty baseline. For one week, count calendar and inbox opens before and after, items repeated unchanged, conflicts resolved before a second ping, and minutes spent checking the briefing. Most important: which alert, digest, or manual check got turned off? If nothing disappears, the briefing did not save time. It gave the same clutter a better layout. What would you require it to retire before keeping it?
