This paper totally ignores the human aspect of sleeping, there is a habit to it.

If we were able to be awake 20 hours a day we may still be miserable because of factors like the sun being down for ane even longer time while we’re awake.

I feel like this is one of those inane pursuits for productivity where that doesn’t fit at all, at least not for the thinking jobs. Maybe in a dystopia big companies like amazon would use inventions like this to be able to let their employees work 20 hour work days or something.

Of course this shouldn’t discredit the linked article of being interesting or anything, just sharing my thoughts on the endless pursuit of productivity.

The article is neutral on the impacts of needing less sleep. It's not proposing an increase in productivity or how to use more waking hours.

Its main raison d'etre is we're all sleep deprived so engineering less sleep may provide health and wellness benefits.

Many people spend a lot of time awake during the darker hours and not everyone is miserable. I actually enjoy both, so if I could operate 20h a day without any harm or loss, it would be a net win for sure (and I also love sleeping).

If you're required to work 8 hours a day, 5 days a week, gaining an extra hour or two per day could go toward leisure or recreation or exercise. Or maybe you're already sleeping only 6.25 hours a night, but it is having negative health and mood effects, and eliminating those negatives could improve quality of life without detracting from waking time.
