I agree and the following is more related to the text you quoted. I interviewed at GS and as soon as I saw the room of clearly exhausted and joyless developers, I could see they actually valued the appearance of work more than productivity. The 40-hour work week was introduced for a reason: https://cs.stanford.edu/people/eroberts/cs181/projects/crunchmode/econ-crunch-mode.html https://cs.stanford.edu/people/eroberts/cs181/projects/crunc... It is sad that 100 years after Ford made the discovery people still don't get this. Team A consistently working 40 hours per week will output more work than Team B working 60+ hours per week. That's true for 60, 80 and especially 95+ hours.
