8h on zoom is far more desirable than 8 hours in person shuffling from meeting room to meeting room for me.
I can have the call in the background while looking at something else without it being impolite. I can eat, drink, or use the restroom at will. I can wear comfortable pants. I can throw laundry into the wash in the couple minute gap between meetings. And when the last meeting ends, I close the laptop and I'm already home, no miserable drive in rush-hour traffic.
Of course, there is something worse than in-person meetings. Which is meetings that are hybrid, with a groups calling into zoom from two different conference rooms in different locations. Those manage to be far worse than just everyone individually joining the zoom. And ironically, that's the type of meeting that becomes common when you force your distributed workforce back to offices split across a dozen locations.
