A secretary. The word you're looking for is "secretary". Having a secretary has always been the preferred way to handle these tasks for the wealthy and powerful. The president doesn't schedule his own meetings and manage his own Outlook calendar, a president/CEO/etc has better things to do.
People just created calendar/email/etc software (like Microsoft Outlook) to let us do it ourselves, because secretaries are $$$$. But let's be real, the ideal situation is having a perfect secretary to handle this crap. That's the point of using AI here: to have an AI secretary.
Managing your own calendar would become extremely 2010 coded, if AI secretaries become a thing. It'd be like how "rewinding your VCR tape" is 1990s coded.
Lots of these YouTubers are using openclaw to replace simple Google/Siri voice queries with something prohibitively complex, expensive and insecure.
Also, people in the 90's didn't have push notifications. We see emails on our watch/phone and can delete/archive/snooze from there. Email triage takes zero time these days and can be done from anywhere. I do get it though if you're someone who is extremely busy and really needs a PA.
Much more likely that the average user is either unemployed or in the leisure class.
