I'm not sure how this context is relevant. The point is that you're supposed to be paying attention and I've not yet met a human that can pay attention to two things at once as well as they can to one. I've met a lot that think they can but not any that actually could. This is why return to office is an attractive option. People are definitely not bringing veggies to chop or laundry to fold to a conference room. And most of them are going to pay attention to a person in their presence talking to them because of basic social niceties. It solves the problem with much less hassle than actually having to identify and cull people who can't handle WFH.
