I think for people who don’t agree with the article, perhaps seeking jobs that are outcome based are ideal. For those that are output based, I think it’s totally reasonable to cut back strategically.
Outputs = Productivity. How much stuff you do.
Outcomes = Efficiency. How much useful stuff you do.
Don't aim to get more stuff done (productivity), rather aim to have less stuff to do (focus / efficiency). Do more with less. Frequent activity & context switching is hardly tied to achievement.
