How would you even measure low productivity time for someone like Musk who has incredible leverage?
For example I was chatting with a friebd about his companies product and it sounds awesome.
Yet for me this was a “low value” conversation as I know I couldnt get my workplace to purchase it.
Musk on the other hand can delegate the evaluation and if it’s a good fit his company will buy it.
So for Musk the same conversation could be very high productivity.
