yeah I think the point is a bit muddied. Academics are always working... to me, the main take-away is that he got 6 days to think, and only had a single day of "disruptive meetings" to help ground/discuss whatever he was thinking...
When I worked in sales I spent my weekends frequently answering emails and improving my knowledge in ways that specifically related to work.
Now I work more in "engineering".. and when I'm gardening, or mowing, driving, I'm thinking about work projects at least half the time.
Just like comedians. They are always playing scenarios in their head and playtesting jokes.
