Working out why the workweek is 5 days, non-negotiably, even if you'd be willing to be paid less in proportion, comes down to realizing that it's being maximized subject to the constraint that everybody would flip out if it was 6, and then working out why it's being maximized.
What it's telling you is that a company would rather have 4 people working 5 days a week than 5 people working 4 days a week. The reason for that is, productivity drops a lot when it's spread out over multiple people. The reason behind that is communication overhead - the more context an individual carries in their heads, the less likely their role will exist on an hourly basis in the industry.
So, if anyone wants AI to give us another day off, we need to think about how it can reduce the cost of "context switching" a whole person on and off a task, without simultaneously formalizing our roles so much that it gives us all five. ;-)
