Maybe its just people are working too much, leading to lower output due to not being fresh. I just wish we could try different things, a 4 day workweek, or a day off every other week and measure productivity. Where I have a hard time is we have a problem but we are changing nothing. Microsoft Japan has showed that a 4 day workweek improved productivity by 40%, so maybe less is more - https://www.npr.org/2019/11/04/776163853/microsoft-japan-say...

Also given that tech has almost fastfood levels of turnover cannot be great, people constantly leaving and knowledge being lost and the intense time sink of training new hires and interviewing not to mention recruiting and scouting out new people is not helping any productivity. Pay people decently, don't work them into the ground and watch your productivity jump. Very simple.
